Surface plasmon resonance (SPR) is the manifestation of a resonance effect due to the
interaction of conduction electrons of metal nanoparticles with incident photons. The …

Several recently developed detection techniques opened studies of individual metal
nanoparticles (1–100 nm in diameter) in the optical far field. Eliminating averaging over the …

We present a detailed study of static and dynamic magnetic behavior of Fe 3 O 4
nanoparticles with average particle sizes< d> ranging from 5 to 150 nm. Bulk-like properties …

Highly stable dispersions of nanosized copper particles with an average particle size less
than 2 nm were synthesized using a straightforward, cost-effective, and green method …

We describe ultraresolution microscopy far beyond the classical Abbe diffraction limit of one
half wavelength (λ/2), and also beyond the practical limit (ca. λ/10) of aperture–based …

We have investigated the optical response of periodic arrays of metallic (gold) nanoparticles
composed of a pair of particles on each lattice site. By varying the interparticle separation …

We report the focusing of surface plasmon polaritons by circular and elliptical structures
milled into optically thick metallic films or plasmonic lenses. Both theoretical and …

Recent advances in optical nanotechnologies by controlling surface plasmon polaritons in
metallic nanostructures demonstrate high potential for subwavelength-scale waveguiding of …

We introduce a carbon nanotube as optical near-field probe and apply it to visualize the
plasmon fields of metal nanostructures in both amplitude and phase at 30 nm resolution …

We report the generation and focusing of surface plasmon polariton (SPP) waves from
normally incident light on a planar circular grating milled into a silver film. The focusing …
