Description	Adsorption of blood plasma proteins on the titanium samples with diffferent surface treatment was investigated by electrochemical impedance spectroscopy. We have received samples of pure titanium and titanium alloy Ti6Al4V the surface of which was either polished or gritted with grains of different diameter. All 4 types of surfaces were then etched with and/or without surface material loss. The AFM and electron microscope image of sample surface was obtained. The profile of the surface was determined by AFM as well.
