电沉积用于葡萄糖氧化酶和金纳米颗粒-硅酸盐网络在氧化铟锡（ITO）玻璃电极上的共沉积。葡萄糖氧化酶在金纳米颗粒-硅酸盐网络中的这种共包埋赋予膜生物催化活性。网络中的金纳米颗粒催化酶反应的副产物H2 O2的氧化和还原。传感器的低工作电位消除了常见干扰物的干扰，如对乙酰氨基酚、抗坏血酸、多巴胺等。
Electrodeposition was used for the codeposition of glucose oxidase enzyme and a gold nanoparticle-silicate network onto an indium tin oxide (ITO) glass electrode. This co-entrapment of glucose oxidase enzyme in a gold nanoparticle-silicate network imparts biocatalytic activity to the film. The gold nanoparticles in the network catalyse the oxidation and reduction of H2O2, the by-product of the enzymatic reaction. The low operating potential of the sensor eliminates the interference from common interferents, such as acetaminophen, ascorbic acid, dopamine, etc.
