Potent Covalent Organic Framework Nanophotosensitizers for Photodynamic Immunotherapy

iNature The photodynamic therapy (PDT) using oxygen-dependent type II photosensitizers is often limited by the hypoxic microenvironment of solid tumors. Type I photosensitizers generate oxygen-independent reactive oxygen species (ROS) under light irradiation, but they suffer from aggregation-caused quenching (ACQ) and low ROS generation efficiency. On December 19, 2024, the team led by Ge Zhishen from … Read more
