In recent years, the basic and applied research based on molecular imprinting biomimetic recognition technology has constantly emerged and makes remarkable progress. As a kind of biomimetic identification material with high specificity and stability, molecularly imprinted polymer has been widely used in the purification of food complex matrix, enrichment of trace target and development of new biomimetic detection strategy. In particular, nanomaterials-based surface molecularly imprinted recognition materials not only overcome the defects of traditional molecular imprinted materials such as low adsorption capacity, uneven identification sites, slow mass transfer rate, but also combine the properties of fluorescence and high sensitivity of nanomaterials with the specific recognition and wide application of molecular imprinting, which have attracted extensive attention in food safety, environmental monitoring and other fields. This paper introduced the researches of nanomaterials-based surface molecularly imprinted materials in food safety detection, and analyzed the properties improvement of surface molecularly imprinted polymer by the introduction of various nanomaterials in detail, in order to provide a theoretical basis for the further study of nanomaterials and surface molecular imprinting in the field of analytical detection.
