Description	Polyethylene (PE) was irradiated with 15 keV O+, P+ and Ar+ ions to the .uences from 3 x 1012 to 1 x 1015 cm-2. Thechanges of surface structure and polarity and oxygen concentration were examined on pristine and as-irradiated PE.The in vitro adhesion of rat 3T3 fibroblasts on the modified PE was evaluated 24 h after inoculation. Degradation of PEis manifested by the creation of conjugated double bonds and oxidation of the PE main chain. It was proved that theimplanted P atoms are chemically bound onto degraded polymer chain. Wettability of the polymer surface is a.ected bythe structure and composition of the modi.ed surface layer. In comparison with pristine PE (i) higher cell adhesion isobserved on implanted PE and (ii) the cells cultivated on implanted PE are larger and their adherence is signi.cantlymore homogeneous. The enhancement of 3T3 cells adhesion is highest and smallest for PE implanted with O+ and Ar+ions, respectively. Highest cell adhesion was observed on PE implanted to the fluence of 1 Polyethylene (PE) was irradiated with 15 keV O+, P+ and Ar+ ions to the .uences from 3 x 1012 to 1 x 1015 cm-2.
