It is predicted by various theoretical studies that nanometer size molecules could be trapped in the strong electromagnetic field due to its steep spatial gradient of the filed intensity. In this study, we have attempted to observe the plasmonic molecular trapping behavior in the mixed solution of 4,4’-bipyridine and 2,2’-bipyridine by surface enhanced Raman scattering measurements. In order to control the molecular optical trapping selectivity, we have introduced the electrochemical potential control into the system. The experimental results would indicate the achievement of the selective control of molecular optical trapping at room temperature in solution.
