Abstract
In view of the existing and potential applications of electrochemical enzymatic catalysis with redox enzymes immobilized on the electrode surface in biosensors, a numerical calculation procedure for simulating their cyclic voltammetric responses is presented. It is applicable to systems involving a redox cosubstrate in solution. The cosubstrates, substrates, products, and inhibitors are assumed to diffuse linearly (planar electrode) between the electrode and the solution. The reactions in which the various forms of the immobilized enzyme participate may be as numerous and intricate as required by the simulation with no other restriction than the computing time. They may, at will, follow or not follow Michaelis-Menten kinetics. Slow charge-transfer cosubstrates are treated in the framework of Butler-Volmer kinetic law.
