通过铜/锌合金的电沉积和锌的化学蚀刻在铜线上制备纳米孔铜膜。通过SEM研究表面形貌。当用于检测安培流动注射系统中的葡萄糖时，多孔铜电极的灵敏度比固体铜高 12 倍。连续使用可达50次（%RSD=5.7）。多孔膜的不同制备提供了可重复的响应（P<0.05）。大肠杆菌培养基中葡萄糖的检测与分光光度技术比较良好（P<0.05）。这种简单的技术可以生产具有良好性能的纳米多孔电极，并且可以轻松应用于其他金属和分析物。
A nanoporous copper film was fabricated on a copper wire by electrodeposition of copper/zinc alloy and chemically etching of zinc. The surface morphology was investigated by SEM. When applied to detect glucose in an amperometric flow injection system the porous copper electrode provided 12 times higher sensitivity than solid copper. It could be continuously used up to 50 times (%RSD=5.7). Different preparations of the porous film provided reproducible responses (P<0.05). Detection of glucose in E. coli cultivation medium compared well with spectrophotometric technique (P<0.05). This simple technique can produce a nanoporous electrode with good performances and can easily be applied to other metals and analytes.
