Cuprous oxide (CuO) nanostructure has been synthesized using an electrochemical method with a two-electrode system. Cu foils were used as electrodes and NH(OH) was utilized as the reducing agent. The effects of pH and applied voltages on the morphology of the product were investigated. The morphology and optical properties of CuO particles were characterized using scanning electron microscopy, x-ray diffraction, and diffuse reflectance spectra. The synthesized CuO nanostructures that formed in the vicinity of the anode at 2 V and pH = 11 showed high uniform distribution, small size, and good electrochemical sensing. These CuO nanoparticles were coated on an Indium tin oxide substrate and applied to detect non-enzyme glucose as excellent biosensors. The non-enzyme glucose biosensors exhibited good performance with high response, good selectivity, wide linear detection range, and a low detection limit at 0.4 μM. Synthesized CuO nanostructures are potential materials for a non-enzyme glucose biosensor.
采用电化学方法，以两电极体系合成了氧化亚铜（CuO）纳米结构。Cu 箔用作电极，NH(OH) 用作还原剂。研究了 pH 值和外加电压对产物形貌的影响。采用扫描电子显微镜、X 射线衍射和漫反射谱对 CuO 颗粒的形貌和光学性质进行了表征。在 2 V 和 pH=11 的条件下，在阳极附近合成的 CuO 纳米结构具有高均匀分布、小尺寸和好的电化学传感性能。将这些 CuO 纳米粒子涂覆在氧化铟锡衬底上，用作检测非酶葡萄糖的优异生物传感器。非酶葡萄糖生物传感器具有高响应、良好选择性、宽线性检测范围和低检测限（0.4 μM）的良好性能。合成的 CuO 纳米结构是一种非酶葡萄糖生物传感器的潜在材料。
