Antibacterial properties of polymeric materials are of primary importance in the biomadical filed. In this paper we presented a method for grafting of antibacterial agents on the relatively inert polymeric surface used for biomedical applications.Grafting of the polymer surface with antibacterial molecules was achieved by air plasma. Three different antibacterial agents were used and the results of our study showed that grafting was succesfull and that the surface exhibited antibacterial properties for the in vitro Staphylococcus aureus and Escherichia coli strains.

Biocompatibility of cardiovascular devices is still problematic, especially in the cases of vascular grafts with smaller diameters. In the present paper the influence of polymer crystallinity on plasma modification and biocompatibility was presented. It was shown that crystallinity of polymeric material influences on surface modification and that oxygen plasma treatment improves proliferation of endothelial cells and reduces adhesion and activation of platelets.
