Ion release and bovine serum albumin (BSA) adsorption on AISI 316L (UNS S31603) electrodes was investigated by performing cyclic voltammetry experiments and electrochemical quartz crystal microbalance (EQCM) analyses simultaneously. The quartz crystals were immersed in phosphate- buffered saline (PBS) solutions containing 2 g L-1 BSA and the potential was swept from 0.1 to -1.2 V vs. Ag/AgCI with scan rates of 50, 75, and 100 mV s-1 The results of cyclic voltammetry tests revealed one anodic and one cathodic peak. These peaks could show iron dissolution and BSA adsorption on 316L resonators. These findings were confirmed by EQCM results in which the 316L gained and lost weight loss during cathodic and anodic scans. In addition, the EQCM results indicated Faradaic dissolution of iron and adsorption of protein-water complexes on 316L. The amount of iron release and protein/water complexes adsorption were 1.49 jjg cm-2in 8.4 s and 590.6 pg cm-2 in 21.4 s, respectively.
