摘要

本文对安培型生物传感器中底物和产物的扩散动力学进行了理论分析。采用同伦摄动法对非线性耦合扩散方程组进行了解析求解。在此,我们报告了有关底物浓度、产物浓度和所有可能的扩散和动力学参数值的电流响应的近似解析表达式。并利用Scilab/Matlab程序对该问题进行了数值求解。通过比较,我们发现解析结果与数值结果非常吻合。

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