Hollow Cu2−xSe-based nanocatalysts for combined photothermal and chemodynamic therapy in the second near-infrared window

Octahedral Cu 2− x Se nanoparticles loaded with the autophagy inhibitor chloroquine (CQ) and targeting neuropeptide Y ligand work as a novel therapeutic platform (Cu 2− x Se@CQ@NPY) to achieve a synergetic CDT/PTT therapeutic outcome for breast cancer.
