Mathematical analysis of an enzyme-entrapped conducting polymer modified electrode

A mathematical model for the enzyme-entrapped conducting polymer modified electrode is discussed. Approximate expressions for the steady state concentration of the various species in the film and the current response of the enzyme electrode are derived. In this work we employ the Homotopy analysis method (HAM) to solve the nonlinear equations. These approximate analytical results are found to be in good agreement with the previously reported limiting case results. The obtained results are valid for the whole solution domain. Also, the redox enzyme in conducting polymer electrode is the most fundamental requirement for the development of amperometric biosensor and biofuel cell elements.
