| 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。

| Abstract: | 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 0.05 to 3.75 mmol/L. The sensor also has better reproducibility and higher stability. |
