Multi‐technique methods involving surface plasmon resonance spectroscopy and atomic force microscopy provide experimental data for the characterization of peptide adsorption on self‐assembled monolayers. A comparative study is carried out in phosphate‐buffered saline (PBS) and potassium phosphate‐buffered (PPB) water to determine the influence of the salt concentration on the adsorption behavior (see figure; Δ G 0 ads : free energy of peptide adsorption, F des : force required for peptide desorption).
