Abstract:
A computational model of a multilayered amperometric biosensor is presented in this paper. Models of biosensors usually simplifies the electrochemistry of biosensors considering that all electrochemical reactions have infinite rates. While in most cases such approximations are tolerable, at lower electrode potentials these models would not be accurate enough. The model proposed in this paper models the electrochemistry occurring during the biosensor operation more accurately, using the Butler-Volmer equation. Computational experiments showed that models with the Butler-Volmer equation may be valuable tools aiding the analysis of the electrochemistry of amperometric biosensors.
