The accumulation of pesticide residues may cause harm to the human body and the environment. Traditional chromatographic methods are limited by stringent testing conditions, so it is necessary to develop convenient and efficient methods for pesticide residue detection. Fluorescence assays have great potential in the development of portable detection tools due to their fast response and intuitive visualization. In this paper, we reviewed nanomaterial-based fluorescent probes for pesticide residue detection that have been reported in recent years, including small molecule probes, metal-organic framework fluorescent probes, fluorescent quantum dot probes, and nanocluster probes. In addition, we describe the design strategy, detection mechanism, and practical application of these probes in detail. The latest progress and application strategies of fluorescent probe detection methods based on nanomaterials are comprehensively discussed, and prospects are proposed.
