Abstract: A dynamic antimicrobial hydrogel based on natural receptor-ligand recognition, and a preparation method and use thereof are provided. A ligand vancomycin and a receptor AA-based material each are first modified with a modification material, and then a photoinitiator is added to prepare a hydrogel material under irradiation of ultraviolet (UV) light. In the hydrogel, a three-dimensional (3D) network structure is formed through crosslinking. After undergoing a fracture under an external pressure, the hydrogel can rapidly heal itself through crosslinking due to a ligand-receptor interaction and a multi-hydrogen-bond interaction, which bio-mimicks a natural ligand-receptor interaction to realize the dynamics of the hydrogel material. The high antiomicrobial activity of vancomycin imparts the functionality of the hydrogel material; and the physiologically-derived monomer improves the biocompatibility and reduces the biological toxicity.

Results show that the osseointegration efficiency of the implant material surface can be improved through its immunomodulatory function and osteoinductive activity.
