In this presentation, we will discuss about the possibility to use metal nanostructures for optical manipulation of molecules adsorbed on the surface by confined light. We can show that plasmonic structure enables to concentrate bi-analyte small molecules via the observation of electrochemical surface-enhanced Raman scattering. As the results, not only the condensation of molecules but also the molecular selective condensation have been conducted via the control of the molecule diffusion on metal surface because of the strongly localized plasmonic field.
