Polystyrene samples were pretreated by oxygen plasma and proliferation of human endothelial cells was studied. We found significant improvement of cell proliferation ally at the initial stage indicating improved biocompatibility.

Improved hemocompatibility of poly(ethylene terephthalate) polymer used for vascular grafts have been reported. The substrates were exposed to oxygen or nitrogen plasma and the adhesion of blood platelets was studied. A dramatic decrease of blood platelets concentration was found on surfaces functionallized with polar groups and explained by reorientation of blood proteins on the substrate surface.
