英文摘要:

      Nanoenzymes are a type of nanomaterials with biocatalytic functions, among which precious metal nanoenzymes have unique advantages in high surface area, electronic magnetism, and optical properties, as well as the ability to bind with proteins and oligonucleotides, and are widely used in food safety detection; colorimetric sensing technology has advantages such as simplicity, low cost, and visualization. The combination of precious metal nanoenzymes and colorimetric sensing technology has become a research hotspot. This article reviewed the application of colorimetric sensing technology based on precious metal nanoenzymes in food safety detection both domestically and internationally. It focused on the characteristics and applications of precious metal nanoparticle sensors, precious metal bound non precious metal particle sensors, precious metal bound organic material sensors, and special precious metal material sensors. It also provides prospects and suggestions for future development, aiming to provide reference for the development of simple, efficient, and low-cost colorimetric sensing rapid detection methods for food safety.
