To control of the motion of individual molecules at room temperature, optical tweezers could be the choice of the methods to realize the desirable selectivity with high resolution in time and space. In this study, we demonstrated plasmonic optical trapping of small molecules at the gap of a single metal nanodimer immersed in an electrolyte solution. In situ electrochemical surface-enhanced Raman scattering measurements proved that the plasmonic structure realized selective molecular condensation leading to the formation of unique mixed molecular phases that were distinct from those under thermodynamic equilibrium in nano scale.
