Ultrathin dielectric gaps between metals can trap plasmonic optical modes with surprisingly
low loss and with volumes below 1 nm3. We review the origin and subtle properties of these …

Cancer photothermal therapy (PTT) has captured the attention of researchers worldwide due
to its localized and trigger-activated therapeutic effect. In this field, nanomaterials capable of …

Plasmonics has emerged as an important research field in nanoscience and
nanotechnology. Recently, significant attention has been devoted to the observation and the …

The excitation of surface-phonon-polariton (SPhP) modes in polar dielectric crystals and the
associated new developments in the field of SPhPs are reviewed. The emphasis of this work …

Localized surface plasmon resonances (LSPR) in lithographically fabricated gold (Au)
nanodisc pairs are investigated using microabsorption spectroscopy and electrodynamic …

Langmuir− Blodgett technique was used to assemble monolayers (with areas over 20 cm2)
of aligned silver nanowires that are∼ 50 nm in diameter and 2− 3 μm in length. These …

Fluorescence is widely used in optical devices, microscopy imaging, biology, medical
research and diagnosis. Improving fluorescence sensitivity, all the way to the limit of single …

Our intuitive understanding of light has its foundation in the ray approximation and is
intimately connected with our vision. As far as our eyes are concerned, light behaves like a …

Molecular surface enhanced Raman scattering (SERS) in compact clusters of 30− 70 nm Ag
nanocrystals has shown single molecule Raman scattering cross sections that are orders of …

SERS is some 35 years old, and the subject of over 11 000 articles. The field of Plasmonics,
and large aspects of Metamaterials are clearly based on concepts that became current as a …
