Abstract
A preparation method of a double-network versatile hydrogel with antibacterial and drug sequential release capabilities is provided in the present disclosure, belonging to the technical field of biological corneas. The preparation method includes the following steps: mixing filipin protein-methacrylate, glycidyl methacrylate functionalized quaternized chitosan, polydeoxyribonucleotide, and lithium phenyl(2,4,6-trimethylbenzoyl) phosphinate with drug-loaded micelles, followed by cross-linking under irradiation of ultraviolet to construct a double-network versatile hydrogel with antibacterial and drug sequential release capabilities.
