Abstract:The adsorption of horse spleen ferritin on gold surface is studied with null ellipsometry and scanning electron microscopy. The high sensitivity and in situ advantage of ellipsometry make it very attractive for studies of ultrathin biomolecular layers. The influence of pH and protein concentration in solution on the adsorption kinetics was interpreted using ex situ scanning electron microscopy shots and computer modeling of the system "prism-gold film-adsorbed layer-solution". It seems that the first fast stag… Show more
