Analytical Expressions Pertaining to the Concentration of Substrates and Product in Phenol-Polyphenol Oxidase System Immobilized in Laponite Hydrogels : A Reciprocal Competitive Inhibition Process

الملخص EN

Theoretical analysis corresponding to the diffusion and kinetics of substrate and product in an amperometric biosensor is developed and reported in this paper.

The nonlinear coupled system of diffusion equations was analytically solved by Homotopy perturbation method.

Herein, we report the approximate analytical expressions pertaining to substrate concentration, product concentration, and current response for all possible values of diffusion and kinetic parameters.

The numerical solution of this problem is also reported using Scilab/Matlab program.

Also, we found excellent agreement between the analytical results and numerical results upon comparison.
