Abstract:
A composition containing a biopolymer matrix comprising constituents selected from the following:a. a methacrylamide modified gelatin and a polysaccharide, wherein the gelatin is modified with methacrylamide side groups which are capable of being radically cross-linked; or b. a gelatin and a vinyl-substituted polysaccharide, wherein the polysaccharide is modified with vinyl side groups which are capable of being radically cross-linked; or, c. a methacrylamide modified gelatin and a vinyl-substituted polysaccharide wherein the gelatin has been modified with methacrylamide side groups which are capable of being radically cross-linked and the polysaccharide has been modified with vinyl side groups which are capable of being radically cross-linked; wherein the respective matrix constituents are physically entrapped in the matrix, after radically induced cross-linking polymerization or radically induced cross-linking copolymerization, so that they form a semi-interpenetrating network.
