Abstract

Wet and dry etching methods were used to physically modify the surface of borosilicate glass for further measurements in roughness-induced protein adsorption. The etching parameters determine the roughness of the glass surface while other parameters are not significantly changed. To exclude a chemical alteration of the surface, the isoelectric points, contact angles, and surface energies were analyzed before and after the etching process.
