Does size matter?- understanding size/area effect on your biosensor

In the adjacent table we have the areas (cm2) of our standard electrodes. This means that with all things being equal then the electrochemical signal from one a sensors changes as a scientist uses these different electrodes, assuming that area is part of the signal intensity. 

From the table with all parameters otherwise being constant we would expect the signal gathered on a ZP101 sensor to be approximately 18.5 times greater than that gathered on the ZP104.

The reason that ZP has different sizes of electrodes is that we expect all our customers to eventually go to market and so an important question will be 'how big does your sensor need to be?' The reason we ask the question is for a number of  reasons including:

 

  1. We can generally reduce the cost of the mass produced sensors as we reduce their size.
  2. Many of our clients and collaborators are working in continuous monitoring biosensors including continuous glucose monitoring and continuous lactate monitoring where the sensors will be implanted and so there small sensors are a necessity.

Zimmer and Peacock are expert contract developers and manufacturers of biosensors, medical diagnostics and continuous monitoring glucose and lactate technologies, if you have any questions regarding these technologies please don't hesitate to contact us.
