Tumor microenvironment responsive and nanozyme‐catalyzed photodynamic therapy via lysosome‐localized copper‐doped carbon dots
The tumor microenvironment (TME), characterized by hypoxia, glutathione (GSH) overexpression and elevated H 2 O 2 , limits photodynamic therapy (PDT) but also offers novel therapeutic tools for antitumor strategies. Herein, lysosome‐localized copper‐doped carbon dots (Cu‐MLCDs) were developed as a TME‐responsiv...
