Nanophotonic devices, which control light in subwavelength volumes and enhance light–
matter interactions, have opened up exciting prospects for biosensing. Numerous …

The present status and development of strong-field nano-optics, an emerging field of
nonlinear optics, is discussed. A nonperturbative regime of light-matter interactions is …

Single-molecule detection has long relied on fluorescent labeling with high quantum-yield
fluorophores. Plasmon-enhanced detection circumvents the need for labeling by allowing …

Quantitative surface enhanced Raman spectroscopy (SERS) requires precise control of
Raman enhancement factor and detection uniformity across the SERS substrate. Here, we …

The past several decades have seen tremendous advances in metal nanoparticle research.
This field involves workers from many different areas, including materials scientists …

When light interacts with a metal nanoparticle (NP), its conduction electrons can be driven
by the incident electric field in collective oscillations known as localized surface plasmon …

This tutorial review surveys the optical properties of plasmonic nanoparticles studied by
various single particle spectroscopy techniques. The surface plasmon resonance of metallic …

Surface plasmons are waves that propagate along the surface of a conductor. By altering the
structure of a metal's surface, the properties of surface plasmons—in particular their …

Nanoantennas for visible and infrared radiation can strongly enhance the interaction of light
with nanoscale matter by their ability to efficiently link propagating and spatially localized …

Noble metal nanoparticles are capable of confining resonant photons in such a manner as
to induce coherent surface plasmon oscillation of their conduction band electrons, a …
