In a biological cell, proteins face a highly complex environment comprising crowding and confinement effects as well as interactions with interfaces, cosolvents, and other biomolecules. In this study, the X-ray reflectivity technique has been used for the in-situ characterization of adsorbed protein layers at solid-liquid interfaces. The adsorption of bovine serum albumin at the hydrophobic polystyrene-water interface has been investigated in the presence and in the absence of salts. The data indicate that enhanced adsorption occurs at high salt concentrations.
