摘要
采用乙基纤维素（EC）和载Pt碳纳米管（CNTs）导电复合材料固定葡萄糖氧化酶（GOD）制备EC-Pt/CNTs葡萄糖氧化酶电极．该电极在0～4mmol／L的浓度范围内检测葡萄糖，灵敏度为0．85μA／mmol·L^-1，浸泡18d后电极活性仍达80％，EC-Pt／CNTs葡萄糖氧化酶电极可望构建葡萄糖传感器．
A glucose oxidative electrode（ GOD）, EC-Pt/CNTs glucose oxidative electrode, was constructed by ethyl cellulose （EC） and Pt/CNTs. The sensitivity of the EC-Pt/CNTs GOD is 0.85 μA/mM in the concentration range of 0 -4 mmol/L of glucose. After dipped in PBS （4℃） for 18 days, the activity of the EC-Pt/CNTs GOD can reach 80%. It is promising for the EC-Pt/CNTs GOD to be used to construct glucose biosensor.
