Chinese Abstract

利用奈米技術改良或革新化學感測器或生物感測器,應用在偵測物種或者生物分子是近年奈米科技很熱門的研究領域,由於抗壞血酸對於人類在生理以及病理研究上有很重要的意義,因此許多研究如何準確地偵測抗壞血酸。然而以各種材料製作的電極用在偵測抗壞血酸上卻有電極毒化、靈敏度不足等問題。 在本研究中,成功結合奈米碳管以及聚苯胺製作出擁有高靈敏度、再現性的抗壞血酸偵測電極,其濃度線性範圍為10-5-10-2M,偵測極限可達10-5M。 在實驗中藉由拉曼光譜、熱重分析儀、掃瞄電子顯微鏡來鑑定奈米碳管以及聚苯胺的性質與形貌;並且進行電極的電化學性質研究發現:奈米碳管能有效提升電極的導電度(電活性)並且降低抗壞血酸的偵測電位;而以電聚合方式聚合在碳管電極上的聚苯胺則可以輔助奈米碳管催化抗壞血酸氧化,並且利用聚苯胺的高穩定性質確保電極的穩定性。

English Abstract

It is very popular that scientists improve or innovate chemical sensor or biochemical sensor for sensing tissues or bimolecular by nanotechnology. Due to the importance of ascorbic acid (Vitamin C, AA) for human being, many studies has been focus on ascorbic acid detection. But developing a chemical sensor for sensing AA has met many problems, such as electrode fouling, lacking of sensitivity or the instability of electrode. In this study, we have successfully combined the multi-walled carbon nanotubes (MWNTs) with polyaniline (PANI) to develop a highly sensitive、repeatable electrode for sensing AA. The linear range of response (LRR) is 10-5-10-2M, and the detection limit (LOD) is 10-5M. We characterized the MWNTs and PANI by Raman spectrum and SEM. We study the electrochemical properties of the electrode and found: MWNTs have several functions for sensing, including the conductivity that can increasing the electroactivity, and lowering the detection potential for AA. PANI which electrodeposited on carbon nanotubes electrode can assist in electrocatalysis to AA, and the stability of PANI ensure the electrode’s stability.
