font face="AdvP497E2" size="1"> The interaction of human serum albumin (HSA) with the surface of nanocrystalline Ti/TiO2 electrodes was studied using electrochemical techniques in 0.1MNaCl at different solution pHs. The adsorbed protein layer that is formed immediately when the protein becomes in contact with the electrode was investigated as a function of solution pH and electrode potential. The surface electrochemical properties were studied by cyclic voltammetry in the presence and absence of HSA. The total charge of the2 electrodes was studied using electrochemical techniques in 0.1M
