Title:
DYNAMIC ANTIBACTERIAL HYDROGEL BASED ON NATURAL RECEPTOR LIGAND RECOGNITION EFFECT, PREPARATION METHOD AND USE
Document Type and Number:
WIPO Patent Application WO/2023/216495
Kind Code:
A1
Abstract:
Provided are a dynamic antibacterial hydrogel based on a natural receptor ligand recognition effect, a preparation method and use, which belong to the field of biomedical materials. First, a modification material is used to modify the ligand vancomycin and a receptor AA-based material, then a photoinitiator is added, and a hydrogel material is obtained under ultraviolet irradiation. The hydrogel undergoes cross-linking to form a three-dimensional network structure. After the hydrogel breaks under external pressure, it rapidly undergoes cross-linking and self-heals due to interactions between the ligand and the receptor and multiple hydrogen bond interactions. The healing mimics natural ligand-receptor interactions and the dynamic properties of the hydrogel material are achieved. The efficient sterilization ability of vancomycin shows the functionality of the hydrogel material. The monomer of physiological origin improves its biocompatibility and reduces biotoxicity. With the combination of the dynamic properties, functionality and biological properties, the hydrogel applies for antibacterial and bacteriostatic purposes and to skin repair.
