Abstract: Common fluorescence visualization sensors (ratiometric, paper-based, and molecularly imprinted fluorescence sensors), fluorescence visualization sensing mechanisms (fluorescence resonance energy transfer, internal filtering effect, photoinduced electron transfer, aggregation-induced burst, aggregation-induced emission, intramolecular charge transfer, metal-ligand charge transfer, etc.) and their determination methods were introduced. The application of fluorescence visualization probes made by luminescent substances such as quantum dots (common quantum dots and biomass quantum dots), organic fluorescence material, and metal fluorescence nanoclusters in the food analysis was reviewed, and the development future was prospected (69 ref. cited).
