Abstract:
Based on the nonlinear plasmonic scattering response to the modulated excitation in time, we realized a single-wavelength super-resolution imaging method on a custom-built system which is named as a scattering saturation STED (ssSTED) microscope. A spatial resolution of λ/7 (65 nm) was obtained on 50 nm gold nanoparticles.
