Abstract
A mathematical model developed by Abdekhodaie and Wu J Membr Sci 33521–31 2009 which describes a dynamic process involving an enzymatic reaction and diffusion of reactants and product inside glucosesensitive composite membrane has been discussed This theoretical model depicts a system of nonlinear nonsteady state reaction diffusion equations These equations have been solved using new approach of homotopy perturbation method and analytical solutions pertaining to the concentrations of glucose oxygen and gluconic acid are derived These analytical results are compared with the numerical results and limiting case results for steady state conditions and a good agreement is observed The influence of various kinetic parameters involved in the model has been presented graphically Theoretical evaluation of the kinetic parameters like the maximal reaction velocity V max and Michaelis–Menten constants for glucose and oxygen K g and K ox is also reported This predicted model is very much useful for designing the glucoseresponsive composite membranes for closedloop insulin delivery
