Chemodynamic therapy (CDT) is a new emerging strategy for the
in situ
treatment of tumors. In the microenvironment of tumor cells, CDT may be achieved through the generation of reactive oxygen species (ROS),
e.g.
, hydroxyl radicals (&z.rad;OH) and singlet oxygen (

O

), which induce the death of tumor cells. Copper (Cu) or other transition-metal ions catalyze the production of &z.rad;OH by hydrogen peroxide (H

O

) through Fenton or Fenton-like reactions. With the development of advanced nanotechnology, nanotherapeutic systems with Cu-based nanostructures have received extensive attention and have been demonstrated for their wide applications in the design and construction of nanotherapeutic systems for CDT, along with multimodal synergistic therapy. Herein, the cutting-edge developments of Cu-based nanostructures in CDT are reviewed and discussed, by focusing on the monotherapy of CDT as well as synergistic treatments by hyphenating CDT with various therapeutic protocols,
e.g.
, photothermal therapy (PTT), photodynamic therapy (PDT), sonodynamic therapy (SDT), and so on. In addition, the potential challenges and future perspectives are described in the improvement of CDT therapeutic efficacy, the enhancement of targeting capability, and mechanistic investigations on CDT therapy.
The recent advances of copper-based nanostructures in the enhancement of chemodynamic therapy have been reviewed.
