In last year’s novel, perspective trend of the surface modification by stimuli polymers intensive has been developed. An important part of these studies is determination of the stimuli surfaces interactions with proteins at different surrounding conditions. In our study we investigated a bovine serum albumin adsorption at different pH and temperatures onto surfaces which is modified by oligoperoxide or oligoperoxide-graft-PNIPAM. We demonstrated that dramatic effect on albumin adsorption plays a medium temperature.
