Abstract Tumor cells exploit abnormal redox homeostasis and the pro‐tumorigenic effect of reactive oxygen species (ROS) to enhance their survival progression. However, excessively high levels ROS can exceed oxidative stress threshold tumor cells, inducing cell death. This occur by selectively elevating concentration H 2 O in through both endogenous exogenous mechanisms. The generated serves as a precursor for toxic ROS, such • OH 1 , via chemodynamic photodynamic therapy, respectively, leading apoptosis, necrosis, ferroptosis.

Chemodynamic therapy (CDT) utilizing the Fenton reaction to convert hydrogen peroxide (H2O2) into cytotoxic hydroxyl radicals (˙OH) has recently drawn extensive interest in tumor treatment. However, therapeutic efficiency of CDT often suffers from high concentrations glutathione (GSH), insufficient endogenous H2O2 and inefficient activity. Herein, a GSH-depleting self-providing nanosystem that can efficiently load copper ions doxorubicin (DOX) (MSN-Cu2+-DOX) induce enhanced chemotherapy is proposed. The results show MSN-Cu2+-DOX could release Cu2+ DOX under acidic conditions. Particularly, both released are available for ˙OH production via Fenton-like CDT. Meanwhile, undergoes reduction Cu+ by depleting overexpressed GSH, thereby enhancing Moreover, not only be used chemotherapy, but also promote generation improve Cu-based reaction.
