Oxygen sensor
Electrochemistry is a well established, acurate way to measure dissolved oxygen. The problem with an implanted oxygen sensor is that the surface of a metal electrode will get fouled by the lipids and proteins abundant in all tissues, which leads to a continuous loss of sensitivity. Hence the development of our carbon paste electrode. The measuring surface consists of a carbon - silicon oil mix which is inert to fouling. It allows for months of sustained, stable oxygen measurements once implanted.
Selectivity:
Due to its abundance and the voltage at which oxygen gets reduced (-650 mV in our system), selectivity is not an issue, the signal from interfering compounds is negligible.
Sensitivity:
Dissolved oxygen can be measured reliably over the full physiological range. The resolution of our electrodes is approximately 1.5 nA / µM dissolved oxygen.
Size:
The oxygen sensor consists of a teflon coated silver wire with an external diameter of 225 uM.
Price:
Euro 300 / electrode. (Reference and auxiliary electrode are required as well).
