摘要

提出了一种利用Ti3C2纳米层修饰的丝网印刷电极同时测定多巴胺和酪氨酸的高灵敏度方法。利用循环伏安法、计时伏安法和差分脉冲伏安法研究了修饰电极表面多巴胺的电氧化。在优化条件下，多巴胺的差分脉冲伏安峰值电流在0.5 ~ 600.0µM范围内随多巴胺浓度线性增加，多巴胺的检出限为0.15µM。

Ti3C2 Nano Layer Modified Screen Printed Electrode as a Highly Sensitive Electrochemical Sensor for the Simultaneous Determination of Dopamine and Tyrosine

A highly sensitive method is proposed for the simultaneous determination of dopamine and tyrosine using a Ti₃C₂ nano layer modified screen printed electrode. The electro-oxidation of dopamine at the surface of the modified electrode was studied using cyclic voltammetry, chrono-amperometry, and differential pulse voltammetry. Under the optimized conditions, the differential pulse voltammetric peak current of dopamine increased linearly with dopamine concentrations in the ranges of 0.5–600.0 µM, and the detection limit of 0.15 µM was obtained for dopamine.
