Application of aggregation-induced emission materials in gastrointestinal diseases.

Aggregation-induced emission (AIE) is a phenomenon characterized by certain fluorescent molecules that exhibit weak or no luminescence in solution but demonstrate significantly enhanced luminescence upon aggregation. Accordingly, AIE materials have successfully addressed the limitations associated with aggregation-caused quenching effects and have made significant progress in the application of various fields of medicine in recent years. At present, the application of AIE materials in gastrointestinal (GI) diseases is mainly in GI imaging, diagnosis and treatment. In this review, we summarize the applications of AIE materials in GI pathogens and GI diseases, including inflammatory bowel disease and GI tumors, and outline combined treatment methods of AIE materials in GI tumor therapy.
