Lipoprotein adsorption was investigated at a range of surfaces by in situ ellipsometry, with the aim of reaching a better understanding of its possibilities and limitations as a biosensor tool in the context of atherosclerosis. Although ellipsometry allows direct investigation of lipoprotein interfacial deposition at surfaces coated with confluent layers of endothelial cells, that is, essentially the full biological system equivalent, a simpler and more robust model system based on proteoheparan sulfate adsorbed via its membrane-anchoring domain at hydrophobic surfaces was found to provide largely the same information. While simplistic, it was found that Ca2+-induced adsorption of a range of lipoproteins involved in atherosclerosis at surfaces coated with proteoheparan sulfate indeed provides some accelerated information on initial atherosclerotic plaque formation, as evidenced by correlations between lipoprotein adsorption and well known clinical effects of lipoprotein composition and of treatment with anti-atherosclerotic drugs of synthetic as well as natural origin.
