Abstract

The gradient force in the electric field induced by the localized surface plasmon resonance (LSPR) could retard the molecular Brownian motion at solid-liquid interface. Up to date, we have already demonstrated the molecular selective manipulation through surface-enhanced Raman scattering (SERS) measurements. However, several effects, such as the solvents, solvation, molecular interaction, and ion pair formation, on molecular manipulation are still unclear. In this study, we have tried to reveal the crucial factors for the efficient control of the molecular manipulation within the LSPR induced electric field through SERS observations using Au array structure.
