摘要
利用电化学修饰GOD工作电极及Ag/AgCl参考电极组装成了检测葡萄糖的GOD传感器．在0．7V的极化电位下，孩传感器对葡萄糖的响应电流小于1μA时，此电流与葡萄糖浓度成正比．传感器线性范围2．0×10-5至1．3×10-3mol／L，响应时间10s，稳定工作寿命150次，测量变异系数为2.73％。
Using a chemically modified GOD working electrode and the modified Pt electrode and a Ag/AgCl electrode, the sensor has been made for detectingglucose. Under positive potcntial of 0.7 V vs. Ag/AgCl, the oxidation currnt ofH202 is less than 1 μA, and it is proportional to the concentration of glucose inPBS. The GOD sensor's linear response range -2.0 × 10-3to 1 .3 ×10-3 mol/L, meanresponse time - 10 s, stable working life - 150 times and coefficient of variation(CV)- 2.73 %.
