Prevention of postsurgical adhesion with photosensitive polygalacturonic acid films

The developments made on a anti-adhesion membrane for clinical use were presented. The membranes were based on polygalacturonic acid with pendent photosensitive cinnamate groups as cross linkers. The photo-induced cross-linked membranes were characterized and evaluated by both in vitro and in vivo studies. Cytotoxicity tests were conducted using a LDH assay kit from BioVision to determine the effect of photo cross linked membrane on cell adhesion and growth.
