We will illustrate how specific adsorption of peptides, amino acids, and surfactants to metal surfaces in aqueous solution is predominantly guided by soft epitaxy and induced charges. Computer simulations using the CHARMM-METAL force field have shown excellent agreement with experimental data with respect to facet specific adsorption, the relative order of amino acid adsorption on gold {111} surfaces, and allow insight into shape control and catalytic properties of metal nanostructures. Examples of peptides in contact with Au, Pd, and Pt surfaces will show details of adsorption and sequence specific design.
