以氧化鈷奈米線修飾網版印刷碳電極之研究

Abstract

奈米材料的技術近二十年來蓬勃發展，由於奈米尺度的材料有很高的表面積，在電化學領域早已被運用來做為燃料電池、鋰電池…等各種電極材料的研究。 我們利用不同的參數去生長 Co 3 O 4 奈米線，直接生長於網版印刷碳電極的工作電極表面上，以其作為修飾電極的材料，使電極表面積大幅增加，改進電極的電化學活性。舉凡磁場、電極表面光滑度、預氧化以及濃液的濃度，都會影響奈米線的生長，將在此篇文章一一探討。其後亦利用修飾後的電極，初步對於葡萄糖濃度做分析，以期非酵素電極應用於血糖測試方面能有所進展。

Nano-material technology was developed rapidly for the past two decades. Because of the high surface area of the nano-scale materials, it has been used for the fuel cells and lithium batteries researching in electrochemistry. We used different parameters for the Co3O4 nanowires growing, and directly grew on the top of screen-printed carbon electrodes as material of modified electrodes for increasing surface area to improve the electrochemical activity. It might affect Co3O4 nanowires growth such as magnetic fields, electrode surface smoothness,pre-oxidation and the concentration of NH4NO3. We discussed how the parameters influence Co3O4 nanowires on growth in this paper. We attempted to use the modified electrodes in glucose concentration analysis at last. We expect the non-enzymatic electrode use on blood glucose test have great progress.
