Detection of microscope-excited surface plasmon polaritons with Rayleigh scattering from metal nanoparticles

Detection of microscope-excited surface plasmon polaritons with Rayleigh scattering from metal nanoparticles

We propose a mapping tool of surface plasmon polaritons (SPPs) excited using an optical microscope. By combining dark-field and confocal microscopy, we can efficiently extract metal nanoparticle-induced Rayleigh scattering from background radiation, thereby leading to state-of-the-art SPP measuremen...
