在这项研究中，我们已经开发出一种敏感和选择性的葡萄糖传感器，使用新的CuO纳米片生长在镀金玻璃基板上的低温生长方法。利用X射线衍射（XRD）和扫描电子显微镜（SEM）对CuO纳米结构进行了表征。CuO纳米片是高度致密、均匀的，并表现出良好的晶体阵列结构。X射线光电子能谱（XPS）技术被应用于CuO纳米片的化学组成的研究，所获得的信息表明纯相CuO纳米片。新型CuO纳米片被用于开发灵敏的和选择性的非酶葡萄糖传感器。测量灵敏度为5.20 × 102 μA/mMcm ~ 2，相关系数为0.998。该传感器具有成本低、结构简单、稳定性好、重现性好、选择性高等优点，可用于葡萄糖的快速检测。
In this study, we have developed a sensitive and selective glucose sensor using novel CuO nanosheets which were grown on a gold coated glass substrate by a low temperature growth method. X-ray differaction (XRD) and scanning electron microscopy (SEM) techniques were used for the structural characterization of CuO nanostructures. CuO nanosheets are highly dense, uniform, and exhibited good crystalline array structure. X-ray photoelectron spectroscopy (XPS) technique was applied for the study of chemical composition of CuO nanosheets and the obtained information demonstrated pure phase CuO nanosheets. The novel CuO nanosheets were employed for the development of a sensitive and selective non-enzymatic glucose sensor. The measured sensitivity and a correlation coefficient are in order 5.20 × 102 μA/mMcm2 and 0.998, respectively. The proposed sensor is associated with several advantages such as low cost, simplicity, high stability, reproducibility and selectivity for the quick detection of glucose.
