ABSTRACT:
A process for producing a photocrosslinked-polysaccharide composition, which comprises: freezing a photoreactive polysaccharide-containing solution comprising a photoreactive polysaccharide in which a photoreactive group is bound to a polysaccharide, an aqueous solvent capable of dissolving the photoreactive polysaccharide, and any one substance selected from the group consisting of alcohol having compatibility with the aqueous solvent, a surfactant and a chelating agent; and irradiating the resulting frozen product with light, and a photocrosslinked-polysaccharide composition obtained by the process.
