Tumor‐Microenvironment‐Activatable Polymer Nano‐Immunomodulator for Precision Cancer Photoimmunotherapy

Cancer nanomedicine combined with immunotherapy has become a promising strategy for treating cancer in terms of safety and potency; however, precise regulation of the activation of antitumor immunity remains challenging. Herein, a smart semiconducting polymer nano-immunomodulator (SPNI), which responds to the acidic tumor microenvironment (TME), for precision photodynamic immunotherapy of cancer, is reported. The SPNI is self-assembled by a...
