Nanozymes, as one of the most efficient reactive oxygen species (ROS)‐scavenging biomaterials, are receiving wide attention in promoting diabetic wound healing. Despite recent attempts at improving the catalytic efficiency of Pt‐based nanozymes (e.g., PtCu, one of the best systems), they still display quite limited ROS scavenging capacity and ROS‐dependent antibacterial effects on bacteria or immunocytes,...
The repair of bone defects in diabetes remains a major challenge in the field of biomedicine because of the disturbance of bone immune homeostasis and the susceptibility of exposed wounds to bacterial infection. Clinically, immunoregulation by removing excessive reactive oxygen species (ROS) effectively promotes diabetic bone defect repair. However, aggressive ROS clearance can disrupt ROS homeostasis,...
