ABSTRACT
Currently, specific cancer-responsive fluorogenic probes with activatable imaging and therapeutic functionalities are in great demand in the accurate diagnostics and efficient therapy of malignancies. Herein, an all-in-one strategy is presented to realize fluorescence (FL) imaging-guided and synergetic chemodynamic-photodynamic cancer therapy by using a multifunctional alkaline phosphatase (ALP)-response aggregation-induced emission (AIE) probe, TPE-APP. By responding to the abnormal expression levels of an ALP biomarker in cancer cells, the phosphate groups on the AIE probe are selectively hydrolyzed, accompanied by in situ formation of strong emissive AIE aggregates for discriminative cancer cell imaging over normal cells and highly active quinone methide species with robust chemodynamic-photodynamic activities. Consequently, the activated AIE probes can efficiently destroy cancer cell membranes and lead to the death of cancer cells within 30 min. A superior efficacy in cancer cell ablation is demonstrated in vitro and in vivo. The cancer-associated biomarker response-derived discriminative FL imaging and synergistic chemodynamic-photodynamic therapy are expected to provide a promising avenue for precise image-guided cancer therapy.
