英文摘要:

      Food mycotoxins (aflatoxin, ochratoxin, zearalenone, deoxynivalenol, etc.) are contaminants that pose a serious threat to food safety and public health. With the increasing global demand for food and the complexity of the supply chain, rapid and sensitive detection of contaminants is essential to maintain public health and well-being. In recent years, the rapid development of nanotechnology has provided new ideas for the detection of mycotoxins in food. Among them, quantum dots, as a new type of fluorescent nanomaterials, are favored in the field of biosensing due to their excellent optical properties and high sensitivity. Taking quantum dots as a starting point, this paper briefly reviewed the basic properties, synthesis, modification and functionalization of quantum dots, focused on their application in the detection of food mycotoxins, discussed the advantages and challenges of quantum dots in food mycotoxins detection, with the aim of providing new ideas for food safety detection and on-site real-time detection, and safeguarding food safety and human health.
