Human body fluid containsvarious types of proteins. Some of the proteins like albumins are negatively charged at a neutral body pH and they tend to react with positively charged ions released from metallic biomaterials. These reactions could result in either forming a deposited film or stripping ions from metallic orthopedic implants. In this study we were interested in studying bovine serum albumin (BSA) adsorption on 316L and Ti alloys in phosphate buffered saline (PBS) solutions by measuring mass variations. The electrochemical quartz crystal microbalance (EQCM) was used to detect both electrochemical variables and the changesof the oscillation frequency. Theoscillation frequency changes wereconverted to mass changes by using Sauerbrey equation. Current changes were monitored during cyclic voltammetry experiments. The cyclic voltammetry experiments were carried out in the potential range of 0.2 to -1.3 V vs. Ag/AgCl with scan rates of 2 5 10 20 mV s-1. The amount of mass deposited in this cathodic region was calculated from charge densities for various scan rates. The increase of scan rate led to a slower mass gain on the 316L and Ti alloys. In general Ti electrode gained heavier weight than 316L. This could show the higher tendency of BSA adsorption and/or the generation of a thicker deposited film on Ti alloy compared with 316L in PBS solutions.
