METHOD FOR PREPARING HYDROGEL OF BULK FORMULATION BY IRRADIATING ELECTRON BEAM AND HYDROGEL PREPARED THEREFROM

摘要

The present invention relates to a method for preparing a hydrogel by irradiating an electron beam to polysaccharides, and a hydrogel prepared therefrom. Specifically, the present invention relates to a method for preparing a hydrogel of bulk formulation by inducing crosslinking without substantially adding a crosslinking agent to polysaccharides such as hyaluronic acid, and a hydrogel of bulk formulation prepared therefrom.
