Application of aggregation-induced emission materials in gastrointestinal diseases

Figure 4 Aggregation-induced emission luminogens treatment of tumor processes by photodynamic therapy and cancer cell damage triggered by generation of reactive oxygen species. A: The process and principle of photodynamic therapy for tumor treatment; B: Aggregation-induced emission photosensitizers accumulate in tumor cells and generate reactive oxygen species to kill tumor cells after illumination. AIEgens: Aggregation-induced emission luminogens; PSs: Photosensitizers; ROS: Reactive oxygen species. Created in Figdraw.
