Nanozymes for regulation of reactive oxygen species and disease therapy

With high catalytic activity and stability, nanozymes have huge advantage in generating or eliminating the reactive oxygen species (ROS) due to their intrinsic enzyme-mimicking abilities, therefore attracting wide attention in ROS-related disease therapy. To better design nanozyme-based platforms for ROS-related biological application, we firstly illustrate the catalytic mechanism of different activities, and then introduce different strategies for using nanozymes to augment or reduce ROS level for the applications in cancer therapy, pathogen infection, neurodegeneration, etc. Finally, the challenges and future opportunities are proposed for the development and application of nanozymes.
