Due to diffraction limit, the optical resolution of a far field light is less than a half of its wavelength, which makes it virtually impossible to “see” subject at the nanoscale. The use of a metallic nanocavity can generate spatially highly confined plasmon with intense field of broad energy distribution. It can break the diffraction limit to visualize a single molecule in real space with the light. Many fascinating properties of the nanocavity plasmon (NCP) have also been found, resulting the plasmonic enhanced stimulating emission, coherent energy transfer, plasmon induced nonlinear electron scattering and super-high resolution Raman images of single molecules. A new theory that describes the interaction between the localized light and the molecule has been developed, which helps to understand the experimental observations and provides also exciting new predictions.
