metallic nanoparticles can exhibit very large optical extinction in the visible spectrum due to localized surface plasmon resonance. spherical plasmonic nanoparticles have been the subject of numerous studies in recent years due to the fact that the scattering response of spheres can be analytically evaluated using mie theory. however a major disadvantage of metallic spherical nanoparticles is ...

in this paper, the interaction between an oscillating dipole moment and a silver nanoparticle has been studied. our calculations are based on mie scattering theory and discrete dipole approximation(dda) method.at first, the resonance frequency due to excitingthe localized surface plasmons has been obtained using mie scattering theory and then by exciting a dipole moment in theclose proximity of...

We observe adhesion sites of a cell on a substrate with high resolution. Since this observation requires interfacial measurements between the cell and the substrate, we employ scanning localized surface plasmon microscopy. We experimentally show that focal adhesion sites of a mouse muscle cell can be observed without fluorescent labeling. We also show that a non-scanning surface plasmon microsc...
