| Summary: | 碩士 === 國立中山大學 === 電機工程學系研究所 === 107 === In this thesis, various copper sulfide (CuS) nanostructures composited with copper oxide (CuO) nanoparticles have been discussed. Nanocomposites are grown on the ITO substrates for non-enzymatic glucose sensing. Different morphologies and thicknesses of the sensing materials have significant effects to the sensitivity and the detection range of the sensors. Various CuS nanostructures are electroplated on the ITO substrate in this study. CuO nanoparticles are decorated on the surface of CuS for modification by RF sputtering system. The CuO/CuS nanocomposites are completed as a double-layered sensing material. By adjusting the concentration of the plating solution and changing the plating time, the morphology and the thickness of CuS can be controlled. We analyze the differences of the sensing material before and after the CuO modification. Sensing performances of the devices to glucose are also been compared.
Based on the results, the sensing material CuS has the best performances by fabricating with 0.15M sodium thiosulfate pentahydrate under plating time of 900 s. Its sensitivity is 132.39μAmM-1cm-2. After the CuO modification, the sensitivity is further improved to 139.86μAmM-1cm-2. The results show that the CuO/CuS nanocomposites have higher sensing ability and wider detection range to glucose. It has great potential for biomedical detection.
