Application Note for measuring glucose in soft drinks

 

The detection of glucose is important in many industries and applications, from the monitoring of glucose for diabetics, to knowing the sugar in a soft drink, to measuring glucose in a bioreactor or cell culture. 

 

In this application note on our website we provide a simple experiment that can be performed outside of a laboratory with readily available drinks from the supermarket and is intended to test and to gather the first data from a glucose sensor. 

 

With a glucose sensor one can perform quantitative and qualitative experiments. A quantitative experiment is where we measure and report the amount of glucose in a drop of blood for example.

 

The application experiment described within this document is a qualitative experiment, which requires no chemicals and can demonstrate a clear response by the sensor to regular coke relative to coke zero which has no sugar. The output from the experiment is qualitative in that the output of the experiment is ‘YES or NO, glucose is present’. Find out more on our website.

ZP Glucose Sensor Coke Application Notev
Adobe Acrobat Document 936.1 KB

INTRODUCTION

The detection of glucose is important in many industries and applications, from the monitoring of glucose for diabetics, to knowing the sugar in a soft drink, to measuring glucose in a bioreactor or cell culture. 

In this application note we provide a simple experiment that can be performed outside of a laboratory with readily available drinks from the supermarket, and is intended to test and to gather the first data from a glucose sensor 

With a glucose sensor one can perform quantitative and qualitative experiments. A quantitative experiment is where we measure and report the amount of glucose in a drop of blood for example, see adjacent figure.

The application experiment described within this document is a qualitative experiment, which requires no chemicals and can demonstrate a clear response by the sensor to regular coke relative to coke zero which has no sugar. The output from the experiment is qualitative in that the output of the experiment is ‘YES or NO, glucose is present’. 


THEORY

In this application we take a Zimmer and Peacock glucose sensor and use it in conjunction with an AnaPot potentiostat, though the potentiostats from PalmSens also work in this application.  

We will demonstrate the change in signal for ZP glucose sensor as we go from coke zero to normal coke. 

A ZP glucose sensor is a Type One Glucose Sensor. A Type One Glucose Sensor typically utilizes glucose oxidase (GOx) as the sensing enzyme and oxygen naturally present in the solution as the mediator. The GOx enzyme catalyses the reaction between oxygen and glucose. with glucose initially converted to glucolactone, whilst the oxygen is converted to hydrogen peroxide. The hydrogen peroxide can diffuse to the working electrode where it is oxidized back to oxygen and two electrons are released to the electrode, these electronics are seen as a current by the potentiostat, see adjacent figure.

The glucose oxidase in the ZP glucose sensors is immobilized, this means that the enzyme is held within a polymer and is not free to diffuse away from the sensor. This immobilized enzyme is a benefit as the sensors can be run in continuous monitoring operation where the sensors are within the sample and continuously measure the glucose signal.  The ZP sensor shares some similarities to those of Dexcom and Medtronic which are also Type One Glucose Sensors with an immobilized enzyme formulation. The ZP glucose sensor can be contrasted with all/most self-monitoring-blood glucose strips (SMBG), where the enzyme formulation is soluble and dissolves into the sample. These SMBG sensors are therefore a onetime use and not suitable for continuous monitoring. 


PRACTICAL

To see a video demonstration of the application described within this document please see this video.

The hardware we use in the application note is the AnaPot and the ZP Glucose sensor.


EXPERIMENTAL STEPS

To perform this experiment please follow these steps.

 

  • STEP ONE – Please place the ZP glucose sensor in the front of the AnaPot, or PalmSens, as shown in the adjacent Figure.

  • STEP TWO - The software is set up in accordance with the adjacent figure.

  • STEP THREE - Adding sample - In the first instance add the coke zero as shown below, see adjacent figure.

  • STEP FOUR - Start the potentiostat - Please start the potentiostat by clicking the button in the software, see adjacent figure.

When the potentiostat is first started and coke zero is on the sensor the signal will look like that in the adjacent Figure.


  • STEP FIVE - Adding a drop of normal coke - After about 200 seconds add 10 microlitres of normal coke to the 100 microlitre drop of coke zero which is already upon the sensor, see the  adjacent figure.

Very quickly the magnitude of the signal increases, as shown in the adjacent figure, this is due to the biochemical reaction and the subsequent oxidation of the hydrogen peroxide on the working electrode of the glucose biosensor.

CLEANING AND STORING THE ELECTRODE

As discussed, the ZP Glucose sensor is a Type One Glucose sensor, the ideal way of storing the sensor is to:

 

• STEP ONE - Rinse the end of the sensors that was in contact with the coke with water, this can be tap water but ideally we use deionized water. 

• STEP TWO – Gently draw the water of the sensor using a tissue, we are just trying to gently dry the sensor before we store the sensor.

• STEP THREE – Please store the sensor in a cool dark place a fridge at approximately 5 degC.  Please note that we recommend these conditions to extend the life of the sensor, but you can leave the sensor out in the air at room temperature, but to get the longest life from the sensors then please use the recommended storage conditions.

Following the connection of the dipolar connectors to the thermocouple it is next necessary to connect to the potentiostat according to the adjacent image.

 

 

The settings on the potentiostat channel that are going to be used shoud be in line with the following...'to setup the potentiostat software with a thermocouple set the measurement technique to Amperometric Detection/Chronoamperometry. Set the current range from 1µA to 1mA. Set all pretreatment settings to 0. In amperometric detection settings set “t equilibration time” and “E dc” to 0. Set the “t interval” and “t run” accordingly to your measurement. An example of the configutration is shown in the adjacent screen shot.


Lastly your potentiostat software will show the temperature data as a current, to convert the current back into temperature use the adjacent equation.

An alternative to traditional glass electrodes

 

Traditional glass pH electrodes have been around for decades, but there has been a question is it possible to get away from traditional glass electrodes and replace them with a technology that could provide the performance of a glass electrode but with the low cost fabrication of techniques such as screen-printing.

 

At Zimmer and Peacock we are striving to get pH sensors to 5 cents or less, and we are on the way to achieving this.

 

A recent analysis of pH sensors from a ZP manufactured pH sensor batch showed we are bringing mass produced low cost screen printed pH sensors to the market.

 

Modern Organic Electrochemistry/Analytical Electrochemistry

 

Electrochemistry has a lot to offer the chemist, it can be used:

 

1) As a reagent free method of oxidation/reduction in organic synthesis.

 

2) Electroanalytical chemistry can be used to rank a series of drugs in their propensity to oxidation when considering their metabolic stability.

 

The issue with electrochemistry of the past was the electrochemical technology. Traditional electrochemical equipment was developed by electrochemists for use by electrochemists. A chemist who wishes to use electrochemical techniques is interested in the product of the experiment and not in the electrochemistry itself.

 

The problems with traditional electrochemistry have been:

 

1) ISSUE ONE - Large bulky potentiostats occupying too big a footprint on the bench space.

 

2) ISSUE TWO - Too many cables; traditional electrochemical experiments involve lots of trailing cables with often five or more cables including: working electrode, reference electrode, counter electrode. grounding cable, sensing cable. The issue is the cabling of an electrochemical experiment can be complex, and errors can take place.

 

3) ISSUE THREE - Traditional electrochemical experiments demand solution volumes of 5 ml to 100 ml. This is a real issue in applications such as medicinal chemistry where the compounds are always scarce.

 

4) ISSUE FOUR - Electrochemists are often using aqueous solutions whilst chemists, organics chemists/synthetic chemists are often using organic solvents. The issue is that the materials used in traditional electrochemical experiments may not always be resistant to organic solvents.

 

Find out more about the Modern Approach to Organic Electroanalytical Chemistry on our website here. 

Gold screen printed electrodes and organic solvents

 

At Zimmer and Peacock we have electrodes for different applications, a SPE that may be good for one application may not work for another application. In this figure you can see the effect of chloroform on one of our electrodes, in this scenario we advise the users to use our gold SPE which are resistant to organic solvents.

Wearable Skin Sensors and understanding the Signal

 

The purpose of this note is to give a brief synopsis of some preliminary work performed at ZP for measuring the electrical properties of skin.

 

At Zimmer and Peacock we develop wearable biosensors for our clients and customers, including: lactate, glucose, potassium, sodium, hydration, perspiration/sweat.

 

In this note we have taken one of our off the shelf sensors and investigated them for measuring the conductivity of the skin, applications of such sensors can be used to monitor the surface of the skin or depending on the excitation signal we use we can penetrate into the skin and determine the conductivity below the top layer of skin.

 

The sensors we used for these conductivity based sensors are shown in this figure. You can find out more on our website here

The Modern Approach to Organic Electroanalytical Chemistry.

Though Zimmer and Peacock are steeped in the traditions of electrochemistry our team have also had careers within the pharmaceutical industry, and so it is from this dual perspective that we provide the AnaPot for organo-electroanalytical chemistry.

 

The AnaPot solves all the ISSUES with traditional electrochemical technologies, including:

 

1) SOLUTION ISSUE ONE - The AnaPot is super lightweight and can be placed in the hand and carried around.

 

2) SOLUTION ISSUE TWO - With ZP there are not cables to the working electrode, counter electrode and reference electrodes.

 

3) SOLUTION ISSUE THREE - The technology from Zimmer and Peacock can  perform an electroanalytical analysis on 100 microliters or less of solution.

 

4) SOLUTION ISSUE FOUR - ZP has built the AnaPot with organic solvents in mind so the technologies are tested against aggressive solvents such as DMF etc.

In this note we have taken one of our off the shelf sensors and investigated them for measuring the conductivity of the skin, applications of such sensors can be used to monitor the surface of the skin or depending on the excitation signal we use we can penetrate into the skin and determine the conductivity below the top layer of skin.

 

The sensors we used for these conductivity based sensors are shown in the adjacent figure.


Having decided which electrode to use one can choose to investigate the different layers of the skin through the  judicial use of frequency. In simplest terms the higher a frequency the more it penetrates into the skin.

 

For this investigation we used one of our off the shelf electrochemical impedance spectrometers.


At Zimmer and Peacock we investigated frequencies up to 1 MHz but the useful information really stopped at approximately 100 kHz. We were able to extract signal from the frequency spectrum by viewing it in the Bode Plot and the Nyquist Plot and using a modelling technique called Equivalent Circuits.


The actual data from the study of putting a ZP electrode on the skin is shown in the adjacent image; what we show is that the data obtained on the skin could be modelled with a simple equivalent circuit, but that was in fact a poor model for the skin and a better model was the Advanced Equivalent Circuit shown in the adjacent figure.


The adjacent image shows both data gathered on the skin and the circuit necessary to understand all the elements that contribute to the signal.


The experimental set-up is shown in the adjacent figure.

 

What was finally interesting was that we were able to get some interesting insight by moving the sensor around the body, which is shown in the adjacent image.

Expensive probes replaced by screen-printed electrodes

 

Expensive probe sensors are used throughout industry, including  the water industry, food industry, pharmaceutical industry etc.

 

The issue with these probes is that they are often complex and therefore expensive to manufacture, and this expense means they cannot be used and discarded, but rather they have to be calibrated, used, decontaminated, recalibrated and re-used.

 

At Zimmer and Peacock we are helping clients, move away from traditional probes for total dissolved solids, pH etc by displacing  them with screen printed equivalent electrodes.

 

When manufactured at volumes these screen printed equivalent electrodes can be factory pre-calibrated, used once by the customer and immediately discarded.

As well as world-leading experts in the field, including the confirmed invited speakers, the workshop aims at postgraduate and early careers researchers to maximise the exchange of knowledge and to provide a new platform for the development of new collaborations in this exciting scientific field.   

ZP in Miami

 

The ZP team and our scientific advisors were out and about in downtown Miami this week.

 

The guys were at the Biosensors Congress 2018, attending the lectures and presenting posters.

 

ZP is the world's leading contract biosensor development and manufacturing business, where we develop, manufacture and commercialize our clients' ideas.

Silver/Silver Chloride contamination of working electrode

 

If you are using screen printed electrodes, either made inhouse or from a third party you may find peaks near 0 V when you run a cyclic voltammogram. What you are seeing is the spillage/contamination of the working electrode by the ink/paste used to make your reference electrode.

 

If you have data that looks like that in the adjacent image then please contact Zimmer and Peacock for an explanation and  a fix.

Expensive probes replaced by screen-printed electrodes

Expensive probe sensors are used throughout industry, including  the water industry, food industry, pharmaceutical industry etc.

 

The issue with these probes is that they are often complex and therefore expensive to manufacture, and this expense means they cannot be used and discarded, but rather they have to be calibrated, used, decontaminated, recalibrated and re-used.

 

At Zimmer and Peacock we are helping clients, move away from traditional probes for total dissolved solids, pH etc by displacing  them with screen printed equivalent electrodes.

 

When manufactured at volumes these screen printed equivalent electrodes can be factory pre-calibrated, used once by the customer and immediately discarded.

Silver/Silver Chloride contamination of working electrode

If you are using screen printed electrodes, either made inhouse or from a third party you may find peaks near 0 V when you run a cyclic voltammogram. What you are seeing is the spillage/contamination of the working electrode by the ink/paste used to make your reference electrode.

 

If you have data that looks like that in the adjacent image then please contact Zimmer and Peacock for an explanation and  a fix.

How many channels can I have?

 

At Zimmer and Peacock we focus on manufacturing and sourcing the best technology for our clients and collaborators,.

 

We were recently asked 'how many channels can I have in a single instrument?'

 

The beauty is that the PalmSens MUX8-RS supplied form Zimmer and Peacock can be daisy chained together to give 128 channels.

 

Each multiplexer has a Link connector which can be used to daisy chain to another MUX8-R2 multiplexer, expanding the number of channels. A maximum of 16 multiplexers can be connected in a daisy chain, giving a maximum of 128 channels. The PSTrace software detects automatically how many multiplexers are daisy chained and shows the available number of channels in the user interface.

MEMS and Sensors 2018 - Grenoble

 

Zimmer and Peacock are delighted to be presenting at MEMS and Sensors 2018.

 

Title: Sensors - From Red Hot Chillies to Patients.

 

Abstract: The future for sensors and biosensor is extremely hot, in this talk Zimmer and Peacock discuss a myriad of sensors and applications both possible and under development. From the measuring of caffeine in coffee, to the detection of sulfite in wine, to the hotness of chillies, to the ions in the blood of patients. ZP sees that the IoT is here and the next stage is chemical and biochemical sensors thought out our home and working lives. In this  talk we discuss what is possible, how to do it efficiently and how to avoid re-inventing the wheel.

Reproducibility of electrodes for R and D versus electrodes for final products

 

At Zimmer and Peacock we are pragmatic industrial electrochemists who see that R and D is just the first step on the route to market.

 

The biggest issue for academia and the R and D effort is the complaint of irreproducibility of electrodes.

 

ZP is unique in that we are the only manufacturer who characterises it's batches of electrodes. Read more on our website here

Recommendation on carbon screen printed electrodes

 

At Zimmer and Peacock we like to be fast on customer requests, we have had a request which was:

 

WE area ca. 15 mm2 

CE: area ca. 50 mm2 

RE: Ag/AgCl, area ca 9 mm2 

Separation between electrodes: ca 1.5 mm Overall size: 1 cm2

Modify the WE with an organic mediator

Required with a fast turn around

 

Zimmer and Peacock would recommend that we modify the A-AC-CAC-202-N; this recommendation is based partly on the specification, that we have stock and because the electrode scales very well with respect to cost if people wish to make a product from it.

 

It should be note that the CE is Ag/AgCl, this is an advantage as it allows the CE to be smaller because the Ag/AgCl redox couple on the CE will keep up with all the electrochemical reaction on WE without having to be large.

Glassy carbon electrodes versus screen printed carbon electrodes

 

At Zimmer and Peacock we use glassy carbon electrodes as part of the electrochemical assay development.

 

In the video we explain that it is not economical to go to market with an electrode that is glass carbon but at ZP we have turned our screen printed electrodes so that assays developed on our glassy carbon electrodes are tanslatable onto a low cost screen printed electrodes platform.

Workflow for building a biosensor strip

 

Zimmer and Peacock has started planning our biosensor factory expansions for our clients growing needs, and in addition building these facilities from the ground up contracts for third parties.

 

In the adjacent figure we show a simplified workflow that takes place in these facilities from incoming to final quality assurance.

 

A biosensor production factory is essentially a facility in which to house this workflow; when one looks at the simplified number of steps it takes to make a biosensor strip them we can understand why biosensors which appear simple to make in the lab, become hard to produce at volume.

 

If you are contemplating automating biosensor production or building a facility then please contact Zimmer and Peacock.

Reproducibility of electrodes for R and D versus electrodes for final products

At Zimmer and Peacock we are pragmatic industrial electrochemists who see that R and D is just the first step on the route to market.

 

The biggest issue for academia and the R and D effort is the complaint of irreproducibility of electrodes.

 

ZP is unique in that we are the only manufacturer who characterizes it's batches of electrodes.

In a recent short study ZP electrodes were analysed against a source of electrodes from another supplier, the researcher remarked that the ZP electrodes were very high grade relative to the competition

 

At ZP our philosophy is if you don't measure it you can't improve it, and so we always encourage researchers to ask their suppliers for test data on the electrodes, and ask how they characterize each batch of electrodes. If they are unable or unwilling to supply it then one should be very cautious.


TESTING

 

The independent researchers tested two types of ZP sensors using three electrochemical techniques:

 

  • Open circuit potentiometry (OCP) of the reference electrode vs an external Ag/AgCl reference electrode was recorded to check its stability in a solution with fixed Cl- concentration (0.1M).
  • Cyclic voltammetry
  • Electrochemical Impedance Spectroscopy.

 

The electrodes they tested were named P and G, which have the ZP part numbers A-AD-GG-110-N and A-AD-GG-101-N respectively. 

 

 

RESULTS

 

Cyclic Voltammogram

 

Five P and G electrodes were tested with a known concentration of ferri/ferrocyanide, and the slope from peak to peak of the cyclic voltammetry were measured, the results were for five different electrodes of two different sets. CV% was 20% for P type and 23% for G type.


Impedance Spectroscopy

 

The independent researchers appreciated that cyclic voltammetry was not appropriate if the electrodes were to be used for an analysis where the assay was based on impedance spectroscopy, conductivity or resistivity, therefore on three of each type of electrode P and G they performed EIS analysis. From the Nyquist plot they calculated Rct, whose coefficient of variance was 28 % and 48 % for the P and G type respectively. 


Open circuit potential (OCP)

 

Finally the scientist wanted to check the referencing potential of the screen printed reference electrode, the P and G Electrodes have the same reference electrode material so there was no difference in the OCP when the reference potential was measured against a lab Ag/AgCl electrode and the screen printed reference electrodes were in 0.1 M chloride solution.

 

Ten RE were tested and the results are in the table below.

Mean potential in 0.1 M chloride ve.s lab reference (Ag/AgCl) Coefficient of variation delta V in 2 minute window
 0.236 V 1 %  <0.001 V

Sign conventions in electrochemistry

 

If you are reading this page you have probably stumbled across it because you are confused by the sign conventions in electrochemistry.  Firstly you are not alone, so many people who are trying to look at electrochemical data are slightly bewildered, including us electrochemists.

 

The reason for this confusion is because whether you are interested in: electronalaysis, biosensor, batteries, fuel cells, capacitors, electrolysis etc you have a different perspective on whether a current and voltage should be displayed with a positive or negative sign.

 

We had an enquiry recently based on this confusion and you can find out more on our website here

Bioinspired detection sensor based on functional nanostructures of S-proteins to target the folate receptors in breast cancer cells

 

Zimmer and Peacock were delighted to be authors on a recent paper for the detection of cancer cells.

 

ABSTRACT

 

Development of biosensors requires a well-organized template to enhance the sensing specificity. Biolog-ical molecules that have the ability to self-assemble into ordered structures can be exploited to construct nanostructures and nanodevices. In this regard, bacterial surface layer proteins (SbpA) have been used as an underlying matrix to bind molecules on the nanometer scale. The present study provides evidence that a gold substrate functionalized with folate-modified SbpA can be used as a sensor for breast cancer cells with superior efficacy over traditional sensors. The developed sensor uses folate to recognize folate receptors, which are highly expressed on the cell membranes of some cancer cells, such as breast cancer cells. To examine the specificity of the developed sensor, folate was used as a binding partner for folate receptors on breast cancer cells (MCF-7), and liver cancer cells (HepG2) were used as the control because they lack folate receptors. The fabricated biosensor comprised a gold surface and are crystallized S-layer protein lattice functionalized with folate and addressed acoustically and electro-chemically. Acoustic studies performed using quartz crystal microbalance with dissipation monitoring(QCM-D) showed the efficiency of the developed biosensor in distinguishing between MCF-7 and HepG2 cells. Despite the ability of QCM-D to recognize cells in situ and in real-time, this biosensor had a limited detection range (1 × 105cells/mL). To confirm the functionality of the developed platform, electrochemical measurements were performed and the obtained results were in agreement with the acoustic sensor and proving the efficiency of the designed sensing layer. The S-layer lattice-folate modified biosensor provides a promising strategy for designing efficient sensing platforms that can be used to diagnose early stage cancers with highly expressed folate receptors.

Sign conventions in electrochemistry

If you are reading this page you have probably stumbled across it because you are confused by the sign conventions in electrochemistry.  Firstly you are not alone, so many people who are trying to look at electrochemical data are slightly bewildered, including us electrochemists.

 

 

The reason for this confusion is because whether you are interested in: electronalaysis, biosensor, batteries, fuel cells, capacitors, electrolysis etc you have a different perspective on whether a current and voltage should be displayed with a positive or negative sign. We had an enquiry recently based on this confusion.

THE ENQUIRY

We had a recent enquiry where two labs were working on the same programme but gave very different looking data, see Figure 1.0.0.

In the data above both labs plot voltage on the x-axis and current on the y-axis, but LAB ONE plotted negative voltages to the left of the zero point and positive to the right hand  side of the zero point, whilst LAB TWO had it in the opposite direction, see Figure 1.0.1.

When Zimmer and Peacock looked at the data in Figure 1.0.0.a little deeper we also saw a second less obvious discrepancy betwen the labs; we realised that they had opposite conventions on the sign of the current. 

 

In LAB ONE they showed a current with a positive sign for the oxidation of a molecule and for the reduction of the molecule they had a negative sign on the current, whilst in LAB TWO they had an opposite convention in that LAB TWO showed the current for the reduction of the molecule with a positive sign and the  oxidation of the molecule as a current with a negative sign, we have illustrated this in Figure 1.0.2.

Though this may sound very unsatisfactory to make an easier comparison of the data it was necessary to rotte it through 180 deg. This does feel deep unsatisfactory a process when you want  simply compare data.

CONCLUSION

 

At Zimmer and Peacock we are electrochemists and we are sometimes confused by which convention is being used , our advice is if you are confused please feel free to send us an enquiry regarding the data you are trying to interpret by clicking the link below.

How to design and manufacture a glucose strip?

Though Zimmer and Peacock design and manufacture sensors for ions, small molecules, proteins, enzymes, RNA, DNA, whole cells and microbes etc, we started a long time back designing and manufacturing glucose strips.

We recently had an enquiry with three questions:

 

  • QUESTION ONE - How to design a new Glucose Strip?
  • QUESTION TWO - How to optimize an enzyme solution formulation?
  • QUESTION THREE? - How to produce test Stips fom A to Z/manufacture strips?

On this page we try to try to provide some technical answers to these questions. We also provide a short cut to all of these questions, which is Zimmer and Peacock have a glucose strip which can be purchased. We particularly recommend this as a way of accelerating your development.

QUESTION ONE - How to design a new Glucose Strip?

 

In order to design a glucose strip one needs to understand the anatomy of a glucose srip, that is why we direct people to our web page 'Hacking the Glucose Strip', on this page we lay out the architecture of a glucose strip. 


We recommend that if people are looking for a substrate to build their first glucose sensors on then the Zimmer and Peacock  Value Sensors are a good place to get some early samples; so they can start their preliminary work on a substrate that looks and feels like a glucose strip.


QUESTION TWO - How to optimize an enzyme solution?

 

If we dig into this question a little deeper there are three parts to this question:

 

1) Part One - How to optimize an enzyme solution in regard to the detection of glucose?

 

2) Part Two - How to optimize an enzyme solution with regard to the handling of the solution and manufacturing with the solution in the manufacturing process?

 

3) Part Three - What is the shelf life of teh strips made from the solution?

 

The answer is that when Zimmer and Peacock optimize any new solution for any new sensor and biosensor application we put more effort into this than anything else. We have calculated that when optimizing a sensor for both function and manufacturing we test over 100,000 strips. Completing this many tests requires a lot of manpower and a highly organised database to analyse all the data,we use a system called Julia to do this.


QUESTION THREE - How to manufacture strip?

 

There are several stages of manufacturing strips depending on how big your market is. ZP has written an article on scaling up manufacturing in the adjacent button.

Dangers of separating sensor development and electronics development

 

In the world of biosensors and medical diagnostics every company wants to develop the electronics themselves, but they are happy to outsource the development and manufacturing of the sensor/biosensor.

 

At Zimmer and Peacock we are contract developers of sensor, biosensors and medical diagnostics and so we are happy to support companies as a contract developer and a contract manufacturer, but we always advise a company if they are developing the electronics to buy a reference system from Zimmer and Peacock. This means that they can test the sensors independently of their electronics which helps these clients to later troubleshoot their electronics.

Biomarkers on the breath

 

Zimmer and Peacock are able to detect analytes and biomarkers on the breath.

 

In this video we talk though the one of the tools we use for simulating breath, which we need when developing sensors specific to compounds carried on the breath.

Sensors - Electrical, chemical and mechanical properties

At Zimmer and Peacock we are always happy to give technical advice when choosing from our product range. We recently had an enquiry where the scientist was looking for chemically resistant screen printed  electrodes.


Email response

Our email response is below...'We have three material combinations that are resistant to organic solvents.

 

If you are interested in carbon working electrodes then I would use this , click here.

 

 

If you are interested in gold then I would use this, click here.

 

 

If you are interested in platinum then I would use this, click here

 

 

Our recommendation is the gold electrodes, followed by the platinum and last the carbon electrodes. The reason we like the gold is because they are chemically and mechanically robust and have low ohmic resistance. The platinum is chemically robust but the platinum is not as hard as the gold so you can't make repeated connection to them as the platinum rubs away. The carbon are good and are chemically resistant but the carbon is more electrically resistant and I show that in a  video, click here..'

 

 

At Zimmer and Peacock we give our clients the right technology for their problem if you have any technical questions don't hesitate to contact us.
