Pathogen-carrying seeds can significantly impact plant growth and development and may lead to serious public health incidents. Modern agriculture heavily relies on synthetic chemical microbicides and physical methods to eradicate pathogens transmitted by plant seeds. To counteract the misuse of microbicides, a class of cationic amphiphilic aggregate-induced emission luminogens (AIEgens) are developed as photodynamic seed sterilization agents. AIEgens function as antimicrobial agents in seed treatment. These materials are engineered to specifically bind to pathogenic microorganisms on seed surfaces. Furthermore, when combined with photodynamic therapy, AIEgens can be activated to produce reactive oxygen species that selectively destroy pathogens. Sterilization experiments with tomato seeds carrying Pseudomonas syringae and mung bean seeds carrying Pseudomonas aeruginosa demonstrate that AIEgens can effectively eliminate both plant and animal pathogens carried by seeds. Therefore, AIEgens offer a promising solution for preventing the spread of seed-borne pathogens.

用于植物光动力种子灭菌的聚集诱导发射发光原

携带病原体的种子会严重影响植物的生长和发育，并可能导致严重的公共卫生事件。现代农业严重依赖合成化学杀菌剂和物理方法来根除植物种子传播的病原体。为了抵消杀微生物剂的滥用，开发了一类阳离子两亲性聚集体诱导发射发光剂（AIEgens）作为光动力种子灭菌剂。AIEgens 在种子处理中起抗菌剂的作用。这些材料经过设计，可与种子表面的病原微生物特异性结合。此外，当与光动力疗法结合使用时，AIEgens 可以被激活以产生选择性破坏病原体的活性氧。对携带丁香假单胞菌的番茄种子和携带铜绿假单胞菌的绿豆种子进行的杀菌实验表明，AIEgens 可以有效消除种子携带的植物和动物病原体。因此，AIEgens 为防止种子传播病原体提供了一种有前途的解决方案。
