摘要
电致化学发光传感技术(Electrochemiluminescence,ECL)是一种结合了电化学和光化学的分析方法,因其可控性强、灵敏度高和响应速度快等优势在食品分析领域引起了广泛关注.ECL是通过改变发射物或共反应物的浓度,使其信号强度发生变化,从而实现对目标物质的灵敏检测.首先,该文总结了经典ECL检测体系及基于新型发射物和共反应物的检测体系,并重点介绍了新型发射物中金属纳米团簇和量子点的最新进展,举例阐述其ECL传感器的结构和检测原理.其次,综述了ECL传感器在食品分析领域中的研究进展.最后对ECL传感技术的未来发展趋势进行了展望,为食品中营养成分和污染物的检测提供参考,同时也促进该技术的进一步研究,助力未来食品检测发展.
Abstract
Electrochemiluminescence(ECL)is an analytical method that combines electrochemistry and photochemistry.It has attracted a lot of attention from researchers in the field of food analysis due to its advantages of high controllability,high sensitivity and fast response time.ECL is the sensitive detection of target substances by varying the concentration of luminophores or co-reactants,resulting in changes in their signal intensity.Firstly,the classical ECL detection system and the novel luminophore and co-reactor based detection system are summarized in this paper.It also focuses on recent advances in metal nanoclusters and quantum dots as novel luminophores,and illustrates the structure and detection principle of their ECL sensors with examples.Secondly,the research progress of ECL sensors in the food analysis field.Finally,the future development trend of ECL sensor technology is predicted.It provides a reference for the detection of nutrients and contaminants in food,and also encourages further research into this technology to support the future development of food testing.
