The adsorption on hydrophobic and hydrophilic silica-based surfaces of the integrin-binding PHSRN peptide and the single-residual-mutated analogues, PHSEN and PHSFN, is investigated by comparative QCM-D, XPS, SFG measurements and molecular dynamics calculations. Endothelial cell cultures on the peptide-functionalized materials highlight their tunable pro- or anti-angiogenic potential.

Nyckelord: sum-frequency generation, interfaces, monolayers, molecules
