Strategies for the construction of new fluorescent nanomaterials in the detection and degradation of pesticide residues in food: From sensing to degradation applications prospects.

Pesticide residues in food have long posed a significant threat to both environmental and human health, and their management and effective degradation remain global challenges. Although traditional detection and degradation methods are increasingly constrained by various conditions, fluorescent nanomaterials, known for their high sensitivity and real-time convenience, are emerging as increasingly powerful tools in pesticide residue applications. This work reviews the typical fluorescent nanomaterials reported over the past five years for application in the field of pesticide residues. Through an analysis of the intrinsic mechanisms and synthesis approaches of these nanomaterials, as well as a comparison of the advantages and limitations of different types, recent developments and application strategies in nanomaterial-based detection and degradation are comprehensively discussed. The main findings indicate that the selective hybridization of fluorescent nanomaterials can address the limitations of the original components. Finally, its future development potential is summarized and discussed, thereby offering a theoretical foundation for the development of novel materials with dual functions in detection and degradation.
