- Abstract
Food quality and safety are crucial public health concerns with global significance. In recent years, a series of fluorescence detection technologies have been widely used in the detection/monitoring of food quality and safety. Due to the advantages of wide detection range, high sensitivity, convenient and fast detection, and strong specificity, quantum dot (QD)‐based fluorescent nanosensors have emerged as preferred candidates for food quality and safety analysis. In this comprehensive review, several common types of QD production methods are introduced, including colloidal synthesis, self‐assembly, plasma synthesis, viral assembly, electrochemical assembly, and heavy‐metal‐free synthesis. The optoelectronic properties of QDs are described in detail at the electronic level, and the effect of food matrices on QDs was summarized. Recent advancements in the field of QD‐based fluorescent nanosensors for trace level detection and monitoring of volatile components, heavy metal ions, food additives, pesticide residues, veterinary‐drug residues, other chemical components, mycotoxins, foodborne pathogens, humidity, and temperature are also thoroughly summarized. Moreover, we discuss the limitations of the QD‐based fluorescent nanosensors and present the challenges and future prospects for developing QD‐based fluorescent nanosensors. As shown by numerous publications in the field, QD sensors have the advantages of strong anti‐interference ability, convenient and quick operation, good linear response, and wide detection range. However, the reported assays are laboratory‐focused and have not been industrialized and commercialized. Promising research needs to examine the potential applications of bionanotechnology in QD‐based fluorescent nanosensors, and focus on the development of smart packaging films, labeled test strips, and portable kits‐based sensors.
