A combination of infrared, surface-enhanced infrared absorption (SEIRA), and density functional theory (DFT) was used to study layer-by-layer growth of dopamine on copper nanostructures (CNS).  It was shown that CNS alter the monolayer adsorption of dopamine.  Surprisingly, these alterations continue into the multilayer.  Dopamine adsorption on CNS is considerably different than adsorption on silver nanostructures.  DFT modeling required a combination of small metal clusters and multiple dopamine molecules (to account for strong intermolecular forces) to accurately simulate experimental results.
