23 Jul Photo-crosslinkable hydrogel and preparation method thereof
Abstract
The invention relates to photo-crosslinkable hydrogel and a preparation method thereof. A matrix of the hydrogel comprises keratin; the keratin contains a plurality of free sulfhydryl groups. The preparation method comprises the following steps: dissolving the keratin into a buffering solution, and adding a photoinitiator; after sufficiently dissolving, illuminating under an ultraviolet lamp to form the photo-crosslinkable hydrogel. According to the hydrogel provided by the invention, the gelling time of materials is short, and the mechanical strength is high; the photo-crosslinkable hydrogel can be used for in-vivo injection and gelling, and has wide application value in the aspects of biomedicines, tissue engineering, medicine delivery and the like.
