摘要：
The adsorption of four proteins, RNase A. HEWL, BSA. and beta-Lac, was examined on the surface of a negatively charged SiO2/TiO2 optical waveguide. The amount of adsorbed protein followed the salt series Mg2+ > Li+ > Na+ > K+ and for anions Cl- > Br- > I- This ordering was attributed to protein adsorption being primarily influenced by changes in hydrophobic interactions between the surface and the protein resulting from differences in water structure arising from the presence of electrolytes (C) 2009 Elsevier B V All rights reserved
