Abstract

L-ascorbic acid (AA, also known as vitamin C) and dopamine (DA) play important roles in human life activities. When their concentrations are abnormal, they will cause diseases. Therefore, it is of great interest to develop an effective strategy to detect AA and DA levels. Here, anodic aluminum oxide (AAO) films were used as templates to fabricate indium-tin (InSn) alloy nanowires (NWs) by vacuum mechanical injection method, and then Pt nanoparticles were coated on the surface of the InSn NWs by means of the “in-situ discharge reduction” method. Subsequently, the composites were exposed in air for heat treatment to synthesize PtO2/indium-tin oxide (ITO) NWs. Finally, PtO2/ITO NWs were reduced under H2 atmosphere to obtain Pt/ITO NWs. The results show that the diameter of the InSn NWs is ∼40 nm and Pt nanoparticles with 2–5 nm are uniformly coated on the surface of the ITO NWs. Additionally, the performance of electrochemical detection of AA and DA on the Pt/ITO NWs electrode is tested by the cyclic voltammetry and differential pulse strip** voltammetry. The Pt/ITO NWs electrode has low detection limits in the detection of AA (66.7 µM) and DA (1 µM), which reveals the good electrochemical detection of AA and DA.

摘要

L-抗坏血酸(AA, 又称维生素C)和多巴胺(DA)在人类生命活动中起着重要作用, 当它们的浓度 异常时就会引起疾病。因此, 开发一种有效地检测AA和DA水**的方法具有重要的意义。以阳极氧化 铝(AAO)薄膜为模板, 采用真空机械注入法制备铟锡(InSn)合金纳米线(NWs), 然后采用原位放电还原 法在InSn 纳米线表面涂覆Pt 纳米颗粒并将复合材料暴露在空气中进行热处理, 以合成PtO2/ITO(氧化铟 锡)纳米线。最后, 在H2气氛下还原PtO2/ITO纳米线, 得到Pt/ITO纳米线。结果表明, 在Pt/ITO纳米 线复合材料中, ITO纳米线直径约为40 nm, Pt 纳米颗粒的粒径为2~5 nm。采用循环伏安法和差分脉 冲伏安法测试了在Pt/ITO NWs 电极上检测AA和DA的电化学性能。Pt/ITO NWs 电极对AA(66.7 μmol/L) 和DA(1 μmol/L)的检出限较低, 表明了电极对AA和DA良好的电化学检测能力。
