摘要：
A microdialysis sensor system for continuous glucose measurements has been developed. The sensor is based on co_immobilzing glucose oxidase (GOD) with the peroxidase on the surface of the silicon bases with Au interdigital electrode using the tetranethoxysilane (TMOS) sol_gel technique. A graduated ("sandwich") immobilizing method is performed to improve the stability and the life time of the co_enzyme system. The result of the optimized co immobilized sensor system demonstrated good agreement between the glucose concentration over the linear range 0.5-50mM and the response time is in the order of less then 2min.
