title: Ellipsometric studies of plasma protein adsorption on membrane polymers for blood purification.
abstract: Description of ellipsometric studies on absorption of the human plasma proteins; albumin (HSA), immunoglobulin G (IgG) and fibrinogen (FGN) to polymer surfaces of polyamide, polysulphone, polyetherpolycarbonate and polyacrylonitrile copolymer. Thin layers of the polymers (20-30 nm) were cast onto silicon dioxide/silicon wafers by a spin-coating procedure. The variations observed in surface concentration and adsorption time of the proteins were significant in all four polymers investigated.
