    摘要: The present invention relates to a biological polysaccharide hydrogel, a preparation method therefor and an application thereof. The biological polysaccharide hydrogel of the present invention is formed by means of the mixing and reaction of two solutions; the first solution is a polysaccharide derivative solution having an aldehyde on a side chain; the second solution is a polysaccharide derivative solution having a primary amine on a main chain or a side chain, or a small molecule compound solution having two or more primary amines. The preparation method of the present invention comprises preparing the first solution and the second solution, and then mixing the first solution and the second solution to form a transparent biological polysaccharide hydrogel. The biological polysaccharide hydrogel of the present invention can be applied as a vitreous substitute.
