摘要: 生物电化学传感器的开发和应用是目前电分析化学研究中的一个重要方向,其中最引人注目的是电流式生物电化学传感器的研究[1-2]。传统的电流式生物电化学传感器的基础电极采用的是能检测氧气和过氧化氢的贵金属电极。本文采用四苯基钴卟啉化学修饰电极代替氧电极, 制成了葡萄糖传感器, 并对其性能进行了研究, 结果满意。

Abstract: A glucose electrode was constructed using a coba't tetraphenyl porphyrin modified elec-trode with response time of less than 4s. A linearship was obtained between the currentdecrease and the glucose concentration in the range of 0.05-0.8mmol/L. The activity of theglucose oxidase kepr unchanged for 3 months in icebax condition. The selectivity was satisfactory.

Key words: biosensor, modified electrode, glucose
