Title:
METHOD FOR PREPARING BIOCOMPATIBLE POLY-γ-GLUTAMIC ACID HYDROGEL BY USING ULTRAVIOLET RAYS
Document Type and Number:
WIPO Patent Application WO/2020/004810
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing a poly-γ-glutamic acid hydrogel by using ultraviolet rays, and a use of a poly-γ-glutamic acid hydrogel prepared by the preparation method. The method for preparing a poly-γ-glutamic acid hydrogel resolves the problem of microbial contamination in a poly-γ-glutamic acid solution, and prepares a poly-γ-glutamic acid hydrogel in a high yield by means of a simple treatment process only, and the improved storage stability in a solution, of the poly-γ-glutamic acid hydrogel, was identified such that a poly-γ-glutamic acid hydrogel prepared by the method for preparing a poly-γ-glutamic acid hydrogel, of the present invention, can be provided as scaffolds for tissue engineering, artificial organs and bioinks for three-dimensional printing.
