食源性致病菌与人类健康密切相关,食源性疾病爆发造成的社会经济损失不可估量。荧光纳米材料具有小尺寸效应、独特的荧光性能以及可以与各种类型检测方法相结合对食源性致病菌进行检测的特性,使得其在近几年来发展迅速。可用于食品安全领域的荧光纳米材料主要有量子点(quantum dots)、复合荧光二氧化硅纳米颗粒(the compact fluorescent silica nanoparticles)、金纳米簇(gold nanoclusters)和碳量子点(carbon quantum dots)4种。本文主要综述了这4种不同荧光纳米材料的特点及优势、荧光颗粒制备方法及在食源性致病菌检测领域的应用。
Food-borne pathogens are closely related to human health, and the socio-economic losses caused by food-borne diseases are immeasurable. Fluorescent nanomaterials, with their small size effect, unique fluorescence properties, and the ability to detect foodborne pathogens in combination with various types of detection methods, have led to their rapid growth in recent years. The fluorescent nanomaterials that can be used in the field of food safety are mainly quantum dots, the compact fluorescent silica nanoparticles, gold nanoclusters and carbon quantum dots 4 Species. This article reviews the characteristics and advantages of these four different fluorescent nanomaterials, the preparation of fluorescent particles and their application in the detection of food-borne pathogens.
