A Novel Fluorescence Tool for Monitoring Agricultural Industry Chain Based on AIEgens

With the development of the global economy, the safety of agricultural production has attracted intense attention. To minimize the risk of harmful ingredients in the whole industry chain, it is very necessary to cover the entire process of safety inspections from planting to production to environmental management. Fluorescence sensing as a promising and powerful screening tool is widely used for the detection of ions, toxic gases, biological molecules and so on. However, traditional fluorescent probes often suffer from aggregation-induced quenching(ACQ) effects, which limits their practical applications. In this regard, aggregation-induced emission luminogens(AIEgens) can perfectly address this notorious issue and have shown great potential in agricultural safety analysis. In this review, we briefly summarize their applications in agricultural safety monitoring, including the fabrication of agricultural film, agricultural sewage treatment and selective detection of harmful residues in agricultural products. The challenge and future development of AIEgens in this field are also discussed and highlighted. Hopefully, this review can inspire more researchers to participate in this fascinating area.
