Bio-interactive and bio-inert materials prepared by plasma deposition of organosilicon thin films on polycarbonate substrates were studied and described in this communication. The atmospheric pressure surface barrier discharge was applied. Nitrogen with small admixture of hexamethyldisiloxane (HMDSO) was used as plasma discharge gas. The zeta potential measurement followed by cell adhesion to polystyrene was used to find optimal values of stability of the cell suspension and cell adhesion to the tested surfaces. The samples of plasma deposited layers were characterized by contact angle measurement.
