Abstract
Artificial enzymes have provided great antimicrobial activity to combat wound infection. However, the lack of tissue repair capability compromised their treatment effect. Therefore, development of novel artificial enzyme concurrently with the excellent antibacterial activity and the property of promoting wound healing are required. Here, we demonstrated the hydrogel-based artificial enzyme composed of copper and amino acids possessed intrinsic peroxidase-like catalytic activity, which could combat wound pathogen effectively and accelerate wound healing by stimulating angiogenesis and collagen deposition. Furthermore, the system possesses good biocompatibility for practical application. The synergic effect of the hydrogel-based artificial enzyme promises the system as a new paradigm in bacteria-infected wound healing therapy.
