【摘要】：基于分子印迹技术的电化学发光分析是近几年刚刚发展起来的新型分析方法,兼具分子印迹技术与电化学发光方法两者的优点,具有高灵敏度、高选择性、可控性好、易于微型化和操作简单等特点,在生命科学、食品安全及环境监测等领域有着广泛的应用前景。本综述简要介绍了常用的电化学发光体系和基本原理,综述了近年来分子印迹电化学发光分析的主要研究进展,对不同类型分子印迹电化学分析的构建方法、原理及所构建方法的性能(包括灵敏度、选择性、检测范围和稳定性等)进行了评述。基于分子印迹技术的电化学发光分析主要可以分为三类:制备固态发光电极、非固态发光电极构建分子印迹电化学发光传感器和分子印迹固相萃取与电化学发光分析联用,其中制备固态发光电极用于构建分子印迹电化学发光传感器最有发展前景。最后,本综述也对分子印迹电化学发光分析今后的发展趋势和方向进行了展望。
[Abstract]:Electrochemiluminescence analysis based on molecular imprinting is a new analytical method which has been developed in recent years. It has the advantages of both molecular imprinting and electrochemiluminescence, and has high sensitivity, selectivity and controllability. Easy to miniaturize and easy to operate, it has a wide application prospect in life science, food safety and environmental monitoring. In this review, the common electroluminescent systems and their basic principles are briefly introduced, and the main research progress of molecular imprinted electroluminescence analysis in recent years is reviewed, and the construction methods of different molecular imprinting electrochemical analysis methods are also reviewed. The principle and performance of the method are reviewed, including sensitivity, selectivity, detection range and stability. Electrochemiluminescence analysis based on molecular imprinting technology can be divided into three categories: preparation of solid-state luminescent electrode, construction of molecularly imprinted electroluminescent sensor and combination of molecularly imprinted solid-phase extraction and electroluminescence analysis. The preparation of solid-state luminescent electrodes for the construction of molecularly imprinted electrochemiluminescence sensors is the most promising. Finally, the development trend and direction of molecularly imprinted electrochemiluminescence analysis are also prospected.
