Biocompatibility of biomaterial designed for the closure of congenital heart defects covalently coated by chitosan/heparin:an in vitro evaluation / 中国实用内科杂志

heparin coating.Conclusion Anti-thrombogenicity in vitro of biomaterials designed for the closure of congenital heart defects can be improved by immobilizing Chi/Hep conjugating onto the surface,but proliferation of HUVEC could be inhibited by Chi/Hep coating.
