Mathematical model of electrochemical behavior of redox cycling sensors

A mathematical model of the novel redox cycling sensor was developed to understand and predict its behavior and thus enable further sensor development. Because of size and the electrochemical matrix used the model could be restricted to diffusion processes in solution and membrane and charge transfer at the electrodes. Contrary to many other electrode models it incorporates electrode processes for both anode and cathode due to the nature of the electroanalytical method. The model was solved for two geometries that allowed comparison to experimental data. The model then served to derive parameters for structural optimization and calibration of manufactured sensors.
