摘要
以氢气泡为模板,利用电化学沉积等手段制备微/纳米多孔普鲁士蓝/金复合材料.通过化学修饰将葡萄糖氧化酶固定于复合材料表面,构建具有高灵敏度的电化学葡萄糖传感器,并采用计时电流法研究该传感器对葡萄糖的电化学催化活性.结果表明,该电化学传感器对葡萄糖的响应速度为7 s,检测线性范围为0.05～ 3.75 mmol/L.此外,该酶传感器还具有良好的重现性和稳定性.
Microporous Prussian Blue/gold composite material was prepared with electrochemical deposition and hydrogen bubble as a template. We designeda highly sensitive electrochemical glucose sensor through immobilizing glucose oxidase on the surface of the composite material. We further employed typical current-time response to investigate its electro-catalytic property to glucose. Results show that its response time is 7 s, and linear detection range is O. 05 to 3.75 mmol/L. The sensor also has better reproducibility and higher stability.
