Luminescent semiconductor quantum dots (QDs) are one of the more popular nanomaterials
currently utilized within biological applications. However, what is not widely appreciated is …

Plasmon resonances in metal nanostructures have been extensively harnessed for light
trap** in mesoporous solar cells (MSCs), including dye-sensitized solar cells (DSSCs) …

Coinage metals, such as Au, Ag, and Cu, have been important materials throughout
history.(1) Although in ancient cultures they were admired primarily for their ability to reflect …

Plasmonic nanoparticles can strongly interact with adjacent fluorophores, resulting in
plasmon-enhanced fluorescence or fluorescence quenching. This dipolar coupling is …

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 …

Light scattering by a small spherical particle, a central topic for electromagnetic scattering
theory, is here considered. In this short review, some of the basic features of its resonant …

Colloidal semiconductor nanocrystals or quantum dots (QDs) are monodisperse crystalline
clusters with physical dimensions smaller than the bulk-exciton Bohr radius, ie, the distance …

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 …

We investigate the fluorescence from dyes coupled to individual DNA-functionalized metal
nanoparticles. We use single-particle darkfield scattering and fluorescence microscopy to …

The fluorescence from a single molecule can be strongly enhanced near a metal
nanoparticle acting as an optical antenna. We demonstrate the spectral tunability of this …
