Ellipsometric study of the adsorption of bovine serum albumin into porous silicon

By A. Tsargorodskaya, A. V. Nabok and A. K. Ray


The method of spectroscopic ellipsometry has been applied to study in situ the adsorption of bovine serum albumin (BSA). The porosity and amount of adsorbed BSA were determined by fitting the ellipsometric data to the Bruggeman effective medium approximation model. The presence of intermediate adsorbed layers of polyelectrolytes was found to increase protein adsorption
