Abstract
Fragmented polysaccharide based hydrogel compositions and methods of making and using the same are provided. The subject polysaccharide based hydrogel compositions are prepared by combining a polysaccharide component with a hydrophilic polymer and a cross-linking agent. Also provided are kits and systems for use in preparing the subject compositions.
