碩士 === 國立臺北科技大學 === 化學工程研究所 === 102 === Nowadays Glucose detection is of great importance in the fields of biological, environmental, and clinical analyses. In this research, we report a zinc oxide ( ZnO ) nanorod powder surface coated with carbon material for non-enzymatic glucose sensor applications through hydrothermal process and chemical vapor deposition method. A series of tests including crystallinity analysis, microstructure observation and electrochemical property investigations were carried out. For the cyclic voltammetric ( CV ) glucose detection, the low detection limit of 1 μM with linear range from 0 μM to 10 μM. With such good analytical performance from simple process, it is believed that the nanocomposites composed of ZnO nanorod powder surface coated with carbon material are promising for the development of cost-effective non-enzymatic electrochemical glucose biosensors.
