Toward understanding amino acid adsorption at metallic interfaces: a density functional theory study
In examining adsorption of a few selected single amino acids on Au and Pd cluster models by density functional theory calculations, we have shown that specific side-chain binding affinity to the surface may occur because of a combination of effects, including charge transfer. Larger binding was calculated at the Pd interface. In addition, the interplay between amino acid solvation and adsorption at the interface was considered from first principles. This analysis serves as the first step toward gaining a more accurate understanding of specific interactions at the interface of biological−metal nanostructures than has been attempted in the past.
