首发时间:2024-08-29
摘要:作为人体必需氨基酸之一的L-色氨酸(TryptopHan,L-Trp)在生物体的新陈代谢和蛋白质合成中发挥着重要作用的同时也严重影响着人体神经系统和精神健康。建立一种准确、高选择性的分析方法对于有效监测L-Trp至关重要。本文通过在玻碳电极(Glassy carbon electrode,GCE)上以循环伏安法(Cyclic voltammetry,CV)电聚合制备了分子印迹聚合物(Molecularly imprinted polymers,MIP)并将其用于L-Trp分子印迹电化学传感器(MIP/GCE)的构建、优化和分析性能测试。该传感器在对L-Trp的检测中,表现出较宽的线性范围、高的灵敏度、低的检出限、突出的选择性、优异的抗干扰能力、良好的重复性、优秀的再现性和较好的稳定性,证明了制备的MIP/GCE在传感领域的独特技术优势和广阔应用潜力。

Preparation of molecularly imprinted electrochemical sensor and its application in L-tryptophan sensing
Abstract:As one of the essential amino acids in human body, L-tryptophan (L-Trp) plays an important role in the metabolism and protein synthesis of organisms, and also seriously affects the human nervous system and mental health. The establishment of an accurate and highly selective analytical method is essential for the effective monitoring of L-Trp. In this paper, molecularly imprinted polymers (MIP) were prepared by cyclic voltammetry (CV) electropolymerization on a glassy carbon electrode (GCE) and used for the construction, optimization and analytical performance test of L-Trp molecularly imprinted electrochemical sensor (MIP/GCE).The sensor showed a wide linear range, high sensitivity, low detection limit, outstanding selectivity, excellent anti-interference ability, good repeatability, excellent reproducibility and good stability in the detection of L-Trp, which proved the unique technical advantages and broad application potential of the prepared MIP/ GCE in the sensing field.
Keywords: analytical chemistry L-Trp electrochemical sensor molecularly imprinted polymers
