英文摘要:

      As a new kind of nanomaterial, gold nanoclusters have the advantages of good biocompatibility, fluorescence, chirality, enzyme simulation and so on, and have a great application prospect in food safety detection. In particular, gold nanoclusters have excellent fluorescence properties, which are mainly characterized by large Stokes shift, tunable fluorescence, and high optical stability. In addition, gold nanoclusters also have catalytic properties similar to natural oxidase, which are more stable than traditional natural enzymes, so they are used for sensing detection. This paper mainly summarized the detection principles and applications of nano-gold clusters in food safety detection in recent 5 years from 2 aspects of fluorescence properties and peroxidase-like properties gold nanoparticles cluster, including metal ions, microbial and biological toxins, pesticides and veterinary drug residues and other aspects, and discussed the challenges for the future development of gold nanoclusters in food safety detection, so as to provide references for the application of gold nanoclusters in food detection.
