Intracellular regulation of small molecule aggregation is challenging. Here, the authors achieved tumor-targeted aggregation of an aggregation-induced emission photosensitizer (AIE-PS), TBmA, using γ-glutamyl transferase, an enzyme overexpressed in tumors, and showed this causes ferroptosis in cancer cells through photodynamic therapy.
