The invention belongs to the field of biological
medicine, and discloses
cornea repair hydrogel and a preparation method and application thereof. The
cornea repair hydrogel is prepared through a cross-linking reaction of an IKK-beta specific small-molecule inhibitor and silk
fibroin, and the preparation method of the
cornea repair hydrogel specifically comprises the following steps of 1, using mulberry silk as a
raw material, performing degumming, dissolving,
dialysis and
centrifugation, and obtaining a silk
fibroin solution; (2) adding a TPCA-1 solution into the silk
fibroin solution obtained in the step (1), and uniformly mixing; and (3) carrying out ultrasonic treatment on the
mixed solution of the silk fibroin and the TPCA-1 obtained in the step (2), and carrying out cross-linking reaction at 37 DEG C to obtain the silk fibroin hydrogel compounded with the TPCA-1. The
cornea repair hydrogel prepared by the invention is hydrophilic gel with a three-dimensional
network structure, has certain adhesion to a cornea injury surface, is suitable for cornea
injury repair, is simple in preparation process, does not use additives such as a denaturing agent, a coagulant and a cross-linking agent in the preparation process, and ensures the
biological activity of TPCA-1 to the greatest extent.
