Key phenomena governing aging of polymer surfaces have been addressed in this paper published in a highly reputable journal in the field of surface engineering. We reported systematic research on adhesion and activation of blood platelets and drew correlations between surface properties and material hemo-compatibility.

Polystyrene samples were pre-treated by oxygen plasma and proliferation of human endothelial cells was studied. We found significant improvement of cell proliferation at the initial stage indicating improved biocompatibility.

Improved hemocompatibility of poly(ethylene terephthalate) polymer used for vascular grafts have been reported. The substrates were exposed to oxygen or nitrogen plasma and the adhesion of blood platelets was studied. A dramatic decrease of blood platelets concentration was found on surfaces functionallized with polar groups and explained by reorientation of blood proteins on the substrate surface.

This paper published in a prominent journal in the field of molecular biology addresses adhesion of blood and cerebrospinal proteins on plasma treated polymer surfaces. We invented a novel nanostructured PNIPAM coating which practically prevents surface adhesion of these proteins.

In this classical journal in the field of vacuum science and technology we described original results on treatment of PET polymer with both oxygen and nitrogen plasma. We explained the role of each plasma radicals and enlightened the observed increase of oxygen functional groups on nitrogen plasma treated samples. The increase of these functional groups was attributed to dissociation of water vapor in our vacuum plasma reactor.
