Electrode Potential-Dependent Studies of Protein Adsorption on TiAlV Alloy.

This article presents the potential-dependent adsorption of two proteins, bovine serum albumin (BSA) and lysozyme (LYZ), on TiAlV alloy at pH 7.4 and 37 °C. The adsorption process was studied on an electropolished alloy under cathodic and anodic overpotentials, compared to the open circuit potential (OCP).

Combined in-situ attenuated total reflection-Fourier transform infrared spectroscopy and single molecule force studies of poly(acrylic acid) at electrolyte/oxide interfaces at acidic pH.

Fundamental adsorption mechanisms of poly(acrylic acid) (PAA) electrolyte/oxide interfaces were analyzed by the combination of in-situ attenuated total reflection-Fourier transform infrared (ATR-FTIR) spectroscopy and single molecule force spectroscopy (SMFS). The approach aims at a fundamental understanding of initial states of polymer fouling in chemical microreactors. While the presented FTIR-data provide information on adsorption and desorption kinetics, SMFS studies reveal the corresponding interfacial and intermolecular forces.
