聚集诱导发光材料在食源性致病菌鉴定和检测中的应用

Application of Aggregation-Induced Emission Materials in the Identification and Detection of Food-Borne Pathogens:A Review

食源性致病菌是当前食品安全事件暴发的主要诱导因素之一,设计新型探针以实现食源性致病菌的快速鉴定和检测对保障食品安全和人类健康具有重要意义。聚集诱导发光(aggregation-induced emission,AIE)材料是近年来发现的一种新型荧光材料,“越聚集,越发光”的特点赋予了该探针材料背景值低、信号强度高、光稳定性强的优势。同时,AIE探针在使用过程中还具有无需洗涤的优点,大大节省了操作时间并减少了样品损失,使其在食源性致病菌鉴定和检测方面受到了科研人员的重点关注。本文对AIE材料在食源性致病菌鉴定和检测方面的应用进行分析和总结,重点讨论了AIE材料在食源性致病菌分型、种类鉴定、活性鉴定以及检测时其分子结构特性与上述功能之间的关系,并对其存在的不足以及未来可能的发展方向进行讨论和展望。

Food-borne pathogens are one of the major factors causing food safety incidents.Therefore,designing new probes for the rapid identification and detection of food-borne pathogens is of great significance to ensure food safety and human health.Aggregation-induced emission(AIE)materials are a new type of fluorescent material that has been discovered in recent years.AIE materials have the characteristics of‘the more aggregated,the more luminescent’,endowing them with the advantages of low background,high signal intensity,and strong light stability.Besides,AIE probes can be used without the need for any washing procedure,greatly saving the operation time and reducing sample loss.AIE probes have been of interest to researchers due to their potential in the identification and detection food-borne pathogens.This paper comprehensively analyzes and summarizes the application of AIE materials in the identification and detection food-borne pathogens,with a focus on the relationship between the molecular structures of AIE materials and their functions of AIE materials in the typing,species identification,and viability determination of food-borne pathogens.This paper also discusses the present shortcomings and possible future directions in this field.
