The invention discloses a recombinant collagen-polyglutamate hydrogel and a preparation method thereof, and relates to the technical field of biomedical materials; the invention utilizes irradiation technology to combine recombinant collagen, polyglutamate and polyethylene The hydrogel wound dressing is formed by cross-linking of glycol, wherein the presence of recombinant collagen improves the biocompatibility of the hydrogel material, and is conducive to the crawling, growth and reproduction of cells, and is conducive to the rapid healing of the wound; Under the action of wound enzymes, collagen and polyglutamate are hydrolyzed to produce a large amount of amino acids, which can further promote the rapid repair of wounds. The linking agent and initiator not only optimize the preparation process of the gel, but also avoid the risk of biological safety caused by residual chemical reagents. |
