| titleOfInvention | A kind of preparation method of long-acting antibacterial and healing-promoting keratin dressing |
| abstract | The invention discloses a preparation method of a long-acting antibacterial and healing-promoting keratin dressing, which comprises (1) completely dissolving a certain amount of regenerated human hair keratin in a 98v/v% formic acid solution, stirring evenly, and forming a keratin solution; (2) Freeze-drying is adopted to obtain keratin freeze-dried sponge; (3) the keratin freeze-dried sponge is activated by plasma treatment; (4) the activated keratin freeze-dried sponge is soaked in recombinant human epidermal growth factor hEGF, disulfide Carry out negative pressure flash explosion in the solution of threitol and N,N-di(decylpropylamino)-mercaptoglycine, and then carry out grafting reaction; (5) centrifugal freeze-drying of the keratin sponge that completes the grafting reaction. The keratin sponge prepared by the invention is a medical material capable of inducing regeneration of damaged parts of skin tissue, and can inhibit the growth of wound microorganisms, stimulate the proliferation of skin fibroblasts, and promote wound healing. |
