Abstract: The present invention relates to an injectable hydrogel capable of providing a hydrogel crosslinking point and biological activity by using epigallocatechin gallate (EGCG), which is a green tea extract and capable of removing radicals in the body, a preparation method thereof, and an application thereof. In the present invention, an EGCG duplex has been introduced into the hydrogel to impart rapid crosslinking and immune response modulating ability to the hydrogel. In addition, EGCG, known as a competitive inhibitor of tyrosinase, has significantly higher reactivity with tyrosinase than reactivity between tyrosine and tyrosinase, and thus tyrosinase derived from Streptomyces avermitilis was used as a crosslinking agent. The present invention has developed a hydrogel system in which an EGCG molecule is introduced into hydrogel, which can be thus used as a cross-linking point, impart tissue adhesive capability, and control an immune response in the body.
