Abstract

A mathematical model has been developed to describe the mechanism for internal mass transfer and enzyme reaction kinetics of an amperometric conductive matrix enzyme electrode. The model is simplified and solved analytically to arrive at a representation for the response slope in the linear range as well as for the response time. This is the first time that the response time of an enzyme electrode is described by a mathematical model. Simulations give information on how the design parameters influence the performance of the electrode for a glucose oxidase catalyzed sensing reaction process. Based on this information, several designs were constructed and tested showing suitable agreement with theoretical predictions. Finally, an optimized electrode was designed and validated.
