Diabetes wounds have extremely complex hyperglycemia, hypoxia and high reactive oxygen species (ROS) microenvironments. Consequently, modulation and management of this microenvironment may provide an updated and improved treatment approach for healing of diabetic wounds. In this case, we develop a multifunctional nano-enzyme (CHA at GOx) for diabetes wound treatment, which is jointly assembled based on special dual ligands (alendronate and dimethylimidazole) driven by Ce and glucose oxidase (GOx). According to the present invention, the activity of GOx is protected, and the simulation activity of superoxide dismutase (SOD) and catalase (CAT) is provided, such that the excess glucose and ROS can be effectively removed; particularly, excessive hydrogen peroxide (H2O2) generated by glucose oxidation reaction can be catalyzed to generate oxygen, so that the oxygen balance of the wound surface is adjusted, and the toxic and side effects of GOx are reduced. In addition, the cerium nano-composite also has the effects of promoting cell proliferation and migration and promoting angiogenesis. In-vitro experiments show that CHA (at) GOx contributes to cell migration and promotes formation of cell tubes. In vivo, wound healing of diabetic mice can be obviously accelerated. In a word, the research shows that co-assembly of the multifunctional nano-enzyme has potential in clinical treatment of diabetic wounds.
