Paper Abstract

Conventionally, super-resolution imaging is achieved by manipulating the on/off switching of fluorophores, or by saturation of fluorescence emission. To prevent the photobleaching of fluorophores, we demonstrate novel superresolution imaging based on saturation of scattering from plasmonic particles, for the first time. With spectral studies, we have confirmed the saturation is directly linked to surface plasmon resonance effect. With the aid of saturation excitation microscopy, plus field concentration due to nonlinear plasmon resonance, we have achieved optical resolution below 80-nm based on scattering. Our study will open up a completely new paradigm for super-resolution microscopy.
