A Novel Microdialysis Glucose Sensor System Based on Co-immobilizing on AU Micro-Electrode by SOL-GEL Technique

Abstract

A microdialysis sensor system for continuous glucose measurements has been developed. The sensor is based on co_immobilizing glucose oxidase (COD) with the catalase by sol-gel technique on the surface of the silicon bases with two pattern of An microelectrodes. A graduated ("sandwich") immobilizing method is performed to improve the stability and the life time of the co_enzyme system. The response of the system was in good order. Above all, we developed a new geometry of bispiral microelectrode and numeric analysis its electrochemical character. Keywords - microdialysis ,co-enzyme,sol-gel, microelectrode
