Patent ID: 11111340

Abstract:
The present invention relates to a method of preparing a poly-γ-glutamic acid hydrogel using ultraviolet ray and to a use of the poly-γ-glutamic acid hydrogel prepared by the method, and the method of preparing poly-γ-glutamic acid hydrogel using ultraviolet irradiation according to the present invention solved the problem of microbial contamination in the poly-γ-glutamic acid solution, and produced poly-γ-glutamic acid hydrogel in high yield by only a simple treatment process, and as it was confirmed that the poly-γ-glutamic acid hydrogel has improved storage stability in a solution, the poly-gamma-glutamic acid hydrogel prepared by the method of preparing the same of the present invention can be provided as a tissue engineering scaffold, artificial organs and bio-ink for 3D printing.
