ZP - fixing problems with sensors and biosensors

THE PROBLEM

At Zimmer and Peacock we develop electrochemical sensors, biosensors and medical diagnostics;  something that is rarely mentioned both in the academic or industrial setting is the reference electrode. Often the reference electrode is silver/silver chloride, but the term not often used but which should be accurately applied is pseudo reference electrode.

 

What this means is that the reference electrode is only a reference electrode under certain conditions  of stable chloride concentration.  In many applications chloride can be considered to be stable and repeatable, for example the chloride concentration in blood, plasma, serum, interstitial fluid etc the chloride concentration is around 135 to 150 mM. In other applications such as urine analysis, water testing, food testing etc, the chloride concentration maybe unknown and maybe a variable. The issue  is that a silver/silver chloride reference electrode has a potential that is effected by the sample's chloride concentration,  this is shown in the adjacent image.

 

The effect of having a pseudo reference electrode is that sensors based on amperometry potentiometry, voltammetry, etc many not function as expected if the chloride concentration is unknown and variable.


THE SOLUTION

ZP has developed a reference electrode that it can apply to its standard products that is insensitive to changes in chloride concentration, please see adjacent image.

Newsletter December 7

Welcome to this week's newsletter from Zimmer and Peacock. This newsletter is a mixture of news, stories and tech notes from Zimmer and Peacock. If you want to subscribe to our newsletter or have any questions regarding Zimmer and Peacock and our passion for biosensor technologies please don't hesitate to contact us.

ZP develops chloride sensor

 

At Zimmer we believe that ion sensors including sodium, potassium and pH are important sensors which is why we are delighted to expand our range with a chloride sensor.

Anatomy of a ZP Sensor

 

This picture is the front side and back side of a ZP sensor, when using these sensors it is important that the connector you use does not cause a short between the front side and backside. If you are planning to use these sensors in a potentiometric mode you of course need to make electrical connection with the working/sense electrode, you can then choose to use the reference or counter electrodes as your reference or short the counter and reference together and have them combined as the reference electrode.

Questions about Zahner

 

At Zimmer and Peacock we are here to help our clients and customers. This week we had an enquiry about the EIS and potentiostats of Zahner that ZP distributes in the Nordics and UK.

 

In the short post below we have answered some of the recent questions we received. 

 

1. The Zahner system can be controlled by windows7/8/10-PC, though the Win10 machine is not supplied';this means that if you have a Win10 machine you can run the software.

 

2. Some of the Zahner potentiostats are advertised as having Controlled voltage: ±15 V / ±5 V, what this means is that you can choose to operate the instrument  at ±15 V or ±5 V; you will use the ±5 V voltage often in  applications like the Gratzel cell etc, whilst you will use the ±15 V setting in power applications like batteries and fuel cells. Switching between ±15 V or ±5 V is an option in the software.

 

3.What is the difference between the compliance voltage and the controlled voltage? Often in an electrochemical cell we will have the working electrode, the counter electrode and the reference electrode. The electrochemist is often interested in controlling the voltage at the working electrode (called controlled voltage), but what we as electrochemists sometimes over look is that the potentiostat then applies another voltage to the cell at the counter electrode called the compliance voltage. The reason that the potentiostat applies this compliance voltage at the counter electrode is because the rate of reaction at the counter electrode needs to be as fast as the rate of reaction/current at the working electrode. So in summary the controlled voltage is what we apply at working electrode, whilst the compliance voltage is what the potentiostat applies to the counter electrode to ensure the rate of reaction at the working electrode is as fast as it need to be.

 

4. Zahner instruments come with extra slots for additional hardware modules, these slots can be used for additonal cards like the TEMP/U and the PAD4. For example the TEMP/U allows for the measurement of parameters such as pH, temperature etc within the electrochemical cell, whilst teh PAD4 is often used to measure 4 electrochemical cells that are in a battery or fuel cell stack.

 

5.The PAD4 is useful in applications where you have for example a series of electrochemical cells stacked together to form a battery. The Zahner potentiostat would allow you to measure the impedance across the entire battery, but if you want to know how individual cells within the batter are performing you can use the PAD4 to measure up to 4 cells within the stack, of course the more PAD4 cards you use the more cells within a stack you can measure.

 

6 The PP211 is often supplied with Zahner CIMPS systems, this is because the Zahner CIMPS system has a light source and the P211 is the 'power supply  to that light source.

At ZP we appreciate that the choice of adhesive materials to attach the sensors to the skin is important, and the choice of materials depends on the: application, the skin type, the demographics of the target market, the expected duration of wear.

 

Clearly an adhesive material has a degree of adhesion, which is not static  with time. The adhesivity can increase with time reaching a maximum before the adhesion begins to decrease; at the same time the skin is also replenishing and so skin cells that we initially in place start to shed, and the adhesive can start to peel away.

 

The material scientists have a number of levers to pull when selecting or designing an adhesive material for a wearable biosensor/sensor application this included : class of compound, specific compound, thickness of adhesive etc.

 

In the adjacent video we show four adhesive attached to the same subject, left for 2 hours and then an attempt is made to remove each adhesive, and it is clear that each material has a different degree of tackiness to the skin.

Long term monitoring of potassium ions

At ZP we are in a continuous mode of improving our sensors. In this recent effort we have studied our potassium sensors for longer period to see the drift as  a function of time.

In the adjacent experiment a ZP potassium sensors were tested at three concentrations of 0.1 mM, 1 mM and 10 mM potassium ion concentration. The sensor was tested this way in three consecutive experiments, within a 45 minute period - see adjacent image.


The sensor was taken out of solution between each experiment (trial) and in this study the sensors showed a change between each trial -  see adjacent image.


We zoomed in on the data at 1 mM potassium to understand the drift on the sensors - see adjacent image.

 

We were able to determine that the potassium sensor showed a change in sensitivity of approximately 6 % per hour when in a constant concentration solution of potassium ions of 1 mM .


The importance of sensor drift on a potassium ion sensor (ISE) depends on the application, if you have any commercial or technical questions regarding Zimmer and Peacock's potassium ISE then please don't hesitate to contact us.

Choosing an SPE

 

 

Zimmer and Peacock is focused on helping our clients and partners get to marker ASAP with electrochemical sensors suitable for field applications.

 

For a screen printed electrode to be commercially successful in the field the following FEATURES are important.

 

1. FEATURE ONE - The sensor must have the potential to be low cost, so to ensure the highest margins.

2. FEATURE TWO - The sensors have to function correctly.

3. FEATURE THREE -The sensors should operate at a low power, with simpler electronics.

 

It is with these FEATURES in mind that ZP has started to promote the ‘value range’ over our first generation of sensors and electrodes. Find out more on our website here.

Choosing an SPE

Zimmer and Peacock is focused on helping our clients and partners get to marker ASAP with electrochemical sensors suitable for field applications.

 

For a screen printed electrode to be commercially successful in the field the following FEATURES are important.

 

1. FEATURE ONE - The sensor must have the potential to be low cost, so to ensure the highest margins.

2. FEATURE TWO - The sensors have to function correctly.

3. FEATURE THREE -The sensors should operate at a low power, with simpler electronics.

 

It is with these FEATURES in mind that ZP has started to promote the ‘value range’ over our first generation of sensors and electrodes.

 

 

In the following sections we discuss why the ZP ‘value’ sensors are superior over the ZP first generation of electrodes.

FEATURE ONE - COST

The ‘value’ sensors are 44 % smaller than the generation one sensors. This means that when manufacturing sensors in processes such as sputtering, flat-bed screen printing, roll-to-roll printing etc one will produce 1.8 times more value sensors for every one ZP sensors.  Clearly the production capacity can be approximately doubled by this simple change with little or no CAPEX expenditure.

ZP also sees the ZP value sensor’s benefits translating into other downfield processes, for example if sensors are functionalized by a digital printing process it is possible to functionalize a sheet of value electrodes and produce  1.8 more sensors before having to do a card/sheet change.

The smaller form factor adds benefits further downstream when it comes to packing, storing and shipping.

ZP does understand that you cannot make a sensor so small that the user can no longer handle the sensors, and so we have surveyed the glucose strip market before coming to the final decision on the value sensor size; we also now have practical experience from our ChilliPot product which is on the market and uses the value sensor form factor. 


FEATURE TWO – CORRECT FUNCTION

ZP employs a number of principles from the glucose strip market and so it is fairly achievable to make microfluidic/capillary fill sensors with electrodes in close proximity to one another and where the sample volumes can be below 1 microliter. 

 

Whilst it is both a nice feature for the clients to have the ability to use sample volumes as small as 300 nL it does introduce an issue not commonly considered by electrochemists, which is ‘what is happening at the counter electrode?’

 

In traditional electrochemical thinking what happens at the counter electrode has been mostly ignored based on the following assumptions:

 

1) ASSUMPTION ONE - The counter electrode has been traditionally large relative to the working electrode.

2) ASSUMPTION TWO - The counter electrode has traditionally been at some distance from the working electrode.

3) ASSUMPTION THREE – Traditionally the solution within the electrochemical cell has been large relative to the electrodes.

 

The three assumption above are used by electrochemists to say that the counter electrode is not so important when understanding the signals within an electrochemical sensor, but these assumptions are not necessarily valid in very small volumes associated with electrochemical sensors and biosensors which have capillary/microfluidic chambers upon them.

 

Let’s consider a thought experiment containing an electrochemical assay which operates by applying 650 mV to the working electrode; in this assay the analyte is oxidized at the working electrode, at the counter electrode an equimolar reduction reaction is occurring in parallel with the working electrode reaction.  The reaction at the counter electrode is often not known or fully characterized and can be influenced by a number of parameters including: the concentration of oxygen, the pH, the current driven at the working electrode. 

Therefore, there are at least three variables that govern what maybe happening at the counter electrode, one thing one can often be certain of when using a traditional carbon platinum or gold electrode which is that the counter electrode electrochemical reaction is at best unclear and often unknown.   

The issue is that the unknown products at the counter electrode may diffuse across to the working electrode and so after some seconds the products of reaction at the counter electrode may start to influence the reactions at the working electrode and therefore introduce an otherwise over-looked and uncontrolled contribution to the signal effect, this is schematically.

 

The diffusion of material from the counter electrode to the working electrode in systems where the electrode spacing is millimeters can happen on the seconds to 10s of seconds time range, and so this event can influence the signal. The observable effects of this diffusion can be numerous, but one possible outcome is an electrochemical feedback loop where the reduction product at the counter electrode diffuses to the working electrode and is subsequently re-oxidized. This re-oxidation in turn causes a further increase in current at the counter electrode which in turn drives further diffusion of reduced material from the counter electrode to the working electrode hence further driving up the current, this is in effect a closed loop electrochemical  feedback system , we illustrate such a scenario in the adjacent figure.


At Zimmer and Peacock we have observed the phenomena described in the figure, and have had it reported to us by others in the glucose strip market. 

With the ZP value sensors we have eliminated this effect by instead of having just a bare carbon, platinum or gold counter electrode we instead have a silver/silver chloride counter electrode. What this means is that if the counter electrode is at a negative voltage then the  silver chloride is reduced to silver which is an insoluble product and therefore will not diffuse to the working electrode; of course the counter to this is if the counter electrode is a positive voltage then the silver is converted to the insoluble silver chloride which again does not diffuse to the working electrode. 

The use of silver/silver chloride on the counter electrode of the ZP value sensor at the very least produces a defined reaction on the counter electrode which would otherwise be an unknown reaction which can have unexpected outcomes.

 

 

Feature 3 – Power

 

Though not a topic often discussed the power it takes to drive an electrochemical sensors and biosensors can be linked to two parameters:

 

1) The working voltage – the voltage applied to the working electrode relative the reference electrode.

2) The compliance voltage – the voltage applied to the counter electrode to ensure that the reaction at the counter electrode is not the rate limiting step to the reaction at the working electrode.

It is often overlooked by sensors designers that the chemistry at the counter electrode can influence the power consumption of the analog electronics; for example, if no particular care is taken on the counter electrode material then the compliance voltage maybe - 0.9 V due to the reduction of water. Therefore if the voltage on the working electrode is  0.25 V, the entire cell potential is 1.15 V. A simple change of material on the counter  electrode to silver/silver chloride means that there is now the potential for a very facile reaction on the counter electrode as silver chloride can be converted into silver, and similarly silver into silver chloride in the case of a positive voltage at the counter electrode. The conversion of silver and silver chloride occurs at a compliance potential close to 0 V and so the cell potential for a sensor where 0.25 V is applied the working electrode will now be approximately 0.25 V, as opposed to the previous 1.15 V. This can result in both simpler electronics running at a lower power duty.

 

SUMMARY

Zimmer and Peacock is promoting it’s value sensors over the more traditional sensors because we see that it offers several commercial and technical advantages over the more traditional sensor form factor.

Zimmer and Peacock is a global leader in contract electrochemical sensor and biosensor development and manufacturing, and this has  generated an interest from our clients for ZP taking our capabilities in sensor manufacturing, hardware manufacturing and software design through to a system for measuring pH in  a microwell format.

 

In this note we describe the system we have been asked to develop and ask anyone interested in collaborating with us on this to contact us, we are specifically interested in scientists, engineers, etc who are interested in using such a system in their work and research.


What are we proposing to do?

At ZP we are proposing to take our electrochemical pH measuring capabilities and apply it to a microplate format.

What we are proposing to do is manufacture a 96 well plate with  a pH sensor in each well, in addition we will take our existing hardware for measuring pH and scale it so that rather than measuring one pH sensor we will  measure 96 pH sensors in parallel.


Software and the user experience.

At ZP we fully understand that the ease of use comes in part from the software so we want a user interface that is easy and intuitive. We will develop two screens:

  • Screen One - a first screen where the current pH in a well is shown and is colour coded to show whether the conditions are acidic, basic or alkali.
  • Screen Two - a second screen is accessed from Screen One and shows how the pH has changed as a function of time.

We understand that some clients will want ot have temperature control and temperature monitoring, we intend to have temperature monitoring built into the plate. The temperature control will be achieved by ZP designing  plate so that it can still be used within existing microplate temperature chambers.


ZP Partners

Zimmer and Peacock is looking for partners who are interested in being the first beta users, and getting early access to the technology. Please don't hesite to contact us if you have any questions regarding this programme.

Wearable Sensors - Statistics and Facts

Wearables, as the name suggests, are gadgets that can be worn. These devices usually have smart sensors and are connected to the internet for data exchange. 

 

THE HISTORY OF WEARABLES

Pulsar’s Calculator Wristwatch can be considered as the first consumer wearable device to achieve global success. In 2000, the first Bluetooth headset was sold and in 2004, the first GoPro was launched. The wearable market is promising, as the number of connected wearable devices worldwide is expected to jump from an estimate of 325 million in 2016 to over 830 million in 2020. 

 

WHO CURRENTLY USES WEARABLE DEVICES

Businesses, military forces and medical professionals have been using wearable technology for decades, but the private consumer market has recently started to feature items such as smart glasses, smart watches, hearables, fitness and health trackers, smart jewelry and smart clothing. The most successful wearable devices on the market are smart watches and health and fitness tracker. In fact, just over 170 million units of wearable wristwear devices are forecast to be shipped in 2020, more than any other wearable category. By 2018, smart watches are forecast to account for about half of all wearable unit sales worldwide. According to another forecast sales of smart watches are to reach 141 million units by 2018 worldwide. Apple’s operating system - watchOS - is the most used smart wristwear operating system at this time. watchOS is forecast to maintain this position until 2020, when Android/Android Wear is projected to become the most used wristwear OS. 

 

 

SMART WATCHES

The leading smart watch vendors are Apple, Samsung, Lenovo, Garmin and Pebble with Apple holding the largest share of the market. Despite its strong position in the smart watch market, Apple is not as strong of a player in the overall wearable industry. With a strong presence in the health and fitness wearable market, Fitbit has been a leader in the wearable industry since 2014, when the company held about 45 percent of the market share. As other companies such as Apple, Xiaomi, Garmin, and Samsung have also released wearable products, Fitbit’s market share has declined to around 20 percent at the end of 2016. In all of 2016 wearable device shipments amounted to about 112 million units. 

 

WHY IS THIS SO BIG AND WHERE ARE WE GOING?

The above statement only hints at the vast business and technological frontier that awaits the entrepreneurial pioneers that are now developing the smart items that will capture and amplify human civilization. Though it seems hyperbole at ZP we cannot over emphasize the magnitude of the opportunity that wearable sensors and biosensors present.  There is something irresistibly and overwhelmingly seductive in the attraction between humans and machines.  The Human-Cyber-Machine interface is addictive, and if you are not convinced then you need only look at pedestrians walking on a busy city street, where the majority are actively engaged with their smart phones.

A skeptic may point to static company growth results at FitBit or GoPro and object, but we believe the reason is that it is easy to measure your heart rate, your breathing or you blood pressure.  These are all data that any user already intuitively knows and so who needs a watch to tell you that you are breathing fast or that your heart rate is elevated after exercise. The next real step is when these companies can successfully integrate biochemical sensors, such as glucose, hydration, drug levels, stress markers, pregnancy hormones, adrenaline etc., etc. into a wearable monitors.  These are data points that are not accessible to the individual, and access to real-time instantaneous results will make a real difference in the behavior of elite athletes, amateur athletes, diabetics, enthusiastic gym goers, the elderly etc.

The border between health trackers and medical diagnostic/tracking devices is blurring and will continue to blur over the next few years.  Digital personalized medicine will be the fashion.  There is a very simple difference between going to the doctor, giving a blood sample and the laboratory processing and reporting the result to the doctor.  And finally, the doctor giving you the results along with an interpretation and a bill, of course.  The home glucose monitors allow a patient to take their blood glucose readings at home or wherever, log the data, make an actionable decision and react appropriately by taking insulin, doing nothing or eating some sugar. Eventually, turning the data over to the doctor and get an interpretation and a bill.  A great concern in society and 21st century civilization is data ownership, who owns the data?  In the case of laboratory results, the doctor owns or controls the data.  In the case of the home glucose monitor the patient owns the data.  As more and more wearable devices are sold and the sensor capabilities increase, this personal data will be controlled or effectively owned by the user.  This is both very powerful and democratic, because the wearable user will/can do quasi-scientific studies on himself and make behavioral decisions, this the essence of the Human-Cyber-Machine interface. As this process continues, the behavior of these individuals, and all of us, will change in unpredictable ways. Just like the smart phone users on the street, people are very likely to become addicted to the experience…’do not try taking these data producing wearables away from people...’

 

 

At Zimmer and Peacock we are a superfriendly team so please don't hesitate to contact us.

Gold electrodes for sensors and biosensors

 

This is an inconclusive post, but at ZP we recently took a look at two electrodes, the intention of both electrodes is for sensing.

 

One of the sensors in the image below is a commercial glucose strip (blue), whilst the other is an R and D electrode (green) from Zimmer and Peacock.

 

The commercial glucose strip was made by vapour deposition and laser ablation, whilst the ZP sensor was made by thick film screen printing.

 

Our expectation when looking under the microscope was that the commercial glucose strip would appear much finer/precise/accurate in it's edges and surfaces relative to the ZP thick film sensor. The actual result was that the screen printed electrode and the vapour deposited electrode looked pretty similar. This doesn't rule out that the vapour deposited electrode is in fact has a smoother and more reproducible surface when manufactured in volume than the screen printed electrodes, but a quick assessment under a microscope said that the two processes gave a similar finish.

 

If you are considering manufacturing and gold electrodes are part of your product then we would say the following 'if you are looking for feature sizes less than 200 microns then vapour deposition is a good technique. If you have electrodes whose feature sizes are greater than 200 microns then thick film printing is probably good enough. At the 1000 micron scale then screen printing is probably/definitely good enough'.

 

Every project and product and application is unique, so please contact ZP to discuss your specific requirements.

Gold electrodes for sensors and biosensors

This is an inconclusive post, but at ZP we recently took a look at two electrodes, the intention of both electrodes is for sensing.

 

One of the sensors in the adjacent image is a commercial glucose strip (blue), whilst the other is an R and D electrode (green) from Zimmer and Peacock.

 

The commercial glucose strip was made by vapour deposition and laser ablation, whilst the ZP sensor was made by thick film screen printing.

 

Our expectation when looking under the microscope was that the commercial glucose strip would appear much finer/precise/accurate in it's edges and surfaces relative to the ZP thick film sensor.

Analysing molecules by electrochemistry

 

There is a commercially and technically important fact that is not widely known, which is ..'if you can analyse a molecule by UV-Vis, Fluorescence Spectroscopy, Colorimetric assay, Surface Plasma Resonance etc then you can probably detect it by electrochemistry as well'..

 

Why use electrochemistry?

If you are looking for a super low cost  and robust detection/analysis/sensing technology, then electrochemistry is probably the best platform for you. Most home use glucose strips on the market are electrochemical and this is because the developers and manufacturers realised that they could make the electrochemical test strips at super low cost, that the electronics were low cost and that the sample, blood, could be analysed without any preparation, purification dilution etc.

 

The issue with electrochemistry

The issue with electrochemistry is that scientist are often taught  optical methods as undergraduates and so the techniques are very familiar to us, but electrochemistry and electroanalytical techniques are not so widely taught. At ZP we see our role in part to give people the tools and training to get started on using electrochemical techniques. Find out more on our website here

At ZP we see our role in part to give people the tools and training to get started on using electrochemical techniques.

 

 

 

 


How to get going?

In this quick tutorial we are assuming that you have some electrodes and a potentiostat sourced from Zimmer and Peacock, if not hopefully the notes are useful.

 

We seven seven steps in getting your first electrochemical data on the molecule of interest for you.

 

1st – I would connect a sensor to the Ana Pot and start the software. Once the connection is established, you should apply the settings according to the attached picture.

 

2nd – I would then pipette a blank solution (e.g. PBS) on the electrodes’ area, about 30 – 40 uL covering all electrodes.

 

3rd – I would the run a CV scan with the settings in step 1 and save the data. This would be the baseline.

 

4th – I would then replace the sensor and pipette a known concentration of molecule (e.g. 10 mg/dL) in solvent (e.g.phosphate buffer solution) on the electrodes’ area, 30 – 40 uL.

 

5th – Run the CV scan and save the data.

 

6th – You can then compare both CV scans and check for oxidation, or reduction, current peaks that do not appear on your baseline (e.g. only phosphate buffer solution). These will correspond to the presence of your molecule

 

7th – You can then test different concentrations of your molecule to see if the peak current detected is proportional to the concentration. If everything goes well, the higher the peak current, the higher is the furosemide concentration.

 

 

For a ZP Platinum sensor start with these settings.

 

 

For a ZP Carbon and Gold sensor start with these settings.

 

 


Initial Data

A client followed this exact advise and their initial data is shown in the adjacent image. it was clear that there was a large difference between the baseline signal and the sample with the compound of interest added.

Next Steps

The initial data above showed that at about approximately 50 mV there was a peak, and above 200 mV there was nothing interesting so the ZP Senior Scientist advised the client to do a second series of experiments, but where the upper voltage was limited to 600 mV and the compound of interest was varied so that we could see whether the peak of interest increased as a function of concentration.

Further data

Our client did as requested and varied the concentration between 0 and 10 mg/dL, by analysing the peak at 50 mV we could see that the peak height is proportional to the concentration of compound of interest; therefore we can conclude that we are able to detect the molecule of interest. 

 

A quick assessment of the data showed that the limit of detection (LoD) for this compound was approximately 1 mg/dL, for some applications this LoD is fine, but for other applications we may need to develop the assay sensitivity further. 


Zimmer and Peacock is super friendly company so feel free to contact us with any technical questions.

Variation in screen-printed electrodes

 

At Zimmer and Peacock we are the only manufacturer of screen printed electrodes, biosensor, sensors and medical diagnostics who wafer-map our electrodes. 

 

For certain types of electrochemical sensors the signal is proportional to the working electrode area and so ZP is unique in that we functionally test the working electrode as part of our manufacturing process. 

 

In the adjacent image we have tested 52 electrodes with a standard solution using cyclic voltammetry. We have measured the peak height and have collected all the data we can see how the signal/peak height changes across the wafer. We can see that for this wafer our coefficient of variation is approximately 10%.

 

If someone was using this wafer to make sensors where the method of analysis was EIS (electrochemical impedance spectroscopy) or an amperometric technique we would report advise that the best variation they could expect is 10%, if they wanted better precision we would select electrodes from the wafer which we would take forward to convert into sensors.

Pt electrodes as biosensors

 

Zimmer and Peacock had a collaborator who was using a ZP platinum sensors in a flow cell. The user was wondering why the signal looked like it was changing at the beginning of the assay.

 

In the adjacent image you can see how the signal was changing when tested with 0 micromolar hydrogen peroxide.

 

The answer to this question can have a number of sources but an obvious answer is that the Pt is undergoing conversion from Pt to PtO2. The observation in the lab is often that someone will use at Pt electrode and the signal may take some time to settle, but then on further use of the electrode the electrode is stable. What we suspect at ZP is that the first time you use a sensor it is Pt but as soon a you apply a voltage, maybe 650 mV vs reference electrode then you will convert the top layer of Pt to PtO2. As the platinum is consumed the current due  to this process diminishes until the signal becomes stable.

At Zimmer and Peacock we support our clients and collaborators in three ways:

 

1) Fundamental Research and Characterization - ZP support the academic and industrial community by the supply and support of the EIS systems from Zahner. 

 

2) The provision of chemical sensors for corrosion environmental monitoring.

 

3) The ZP ability to reduce potentiostat systems down to low cost potentiostats.

Oxford University senses spicy deal with Zimmer and Peacock

 

Oxford University Innovation licenses sensors for garlic, ginger and turmeric to Zimmer and Peacock.

 

Handheld devices which can accurately detect and quantify the levels of garlic, ginger and turmeric in foodstuffs form the basis of a new licensing deal between Oxford University Innovation (OUI), the research commercialisation arm of Oxford University, and electrochemical sensor manufacturer Zimmer and Peacock (ZP).

 

The sensors were developed by Professor Richard Compton and his team at the Compton Group in the Oxford University Department of Chemistry, which also developed calibration free pH measurement. The palm-sized devices utilise electrochemical sensing to analyse a liquid sample much the same way a diabetic monitor blood sugar and delivers results to a smartphone or other display in less than a minute.

 

The Compton Group and ZP deal builds on a pre-existing relationship following the prior licensing of ChilliPot, a sensor which provides an accurate measurement of a chilli’s spiciness.

Dr Martin Peacock, CEO at Zimmer and Peacock, said:

 

“It’s great to be able to take the latest developments from the Richard’s lab and then use our skills to develop and market them to the customers. Our products must be easy to use and these electrochemical sensors lend themselves well to compact electronics integrated through to simple smartphone apps.  We’re always keen to learn about the sensing issue that Richard and his group decide to tackle next.”

 

Prof Compton added:

 

“I am delighted to see our sensors being developed by the capable and experienced team at Z&P. They understand the science, the market, and have an impressively dynamic and proactive approach.”

 

Andrew Bowen, Senior Licensing and Ventures Manager at Oxford University Innovation, added:

 

“We think ZP is the perfect partner for developing these latest electrochemical sensors to emerge from Professor Compton’s work.  They bring a wealth of technical and commercial experience, have a prior relationship with the Compton Group, and have already set up a dedicated team to bring these products to market, working with customers to ensure the sensors can meet their individual needs.”
