摘要：
A visible light-curable chitosan derivative, a hydrogel thereof, and a preparation method therefor are disclosed. The visible light-curable glycol chitosan derivative is curable by light in the visible light range and has a wound healing activity. A hydrogel obtained by cross-linkage of the visible light-curable glycol chitosan derivative using visible light has a wound healing effect per se, and further, a hydrogel obtained by cross-linkage in a combination of one or more growth factors has an excellent wound healing effect. In addition, a glycol chitosan hydrogel that can prevent the denaturation of contained drugs and growth factors due to the cross-linkage by visible light and is optimized for application to a wet dressing dosage form can be prepared.
