The sequential adsorption of human serum albumin (HSA), immunoglobulin G (IgG), and fibrinogen (Fgn) at hexamethyldisiloxane (HMDSO) plasma polymer surfaces was investigated with ellipsometry and total internal reflection fluorescence spectroscopy (TIRF) as a function of adsorption time, pH, and excess electrolyte concentration. HSA was found to self-exchange very slowly ( approximately hours) at pH 7.2, irrespective of adsorption time in the range 90 s to 90 min. Preadsorbed HSA was exchanged… CONTINUE READING
