Photocrosslinkable polysaccharides based on chondroitin sulfate [PDF]

Journal of Biomedical Materials Research Part A, 2003
AbstractPhotopolymerizing hydrogels have demonstrated potential for use as a scaffold in numerous tissue‐engineering applications. The majority of photopolymerizing hydrogels are made from purely synthetic polymers. The purpose of this study was to synthesize and characterize photopolymerizing hydrogels derived from the biopolymer chondroitin sulfate ...
