Localized surface plasmon resonance (LSPR) is a longstudied nanoscale phenomenon of
considerable recent interest. 1, 2 These resonances, associated with noble metal …

The vivid optical properties of noble metal nanoparticles have been an object of fascination
since ancient times. The ruby red of stained glass windows arises from gold nanoparticles …

Optical tweezers and associated manipulation tools in the far field have had a major impact
on scientific and engineering research by offering precise manipulation of small objects …

We experimentally demonstrate a perfect plasmonic absorber at λ= 1.6 μm. Its polarization-
independent absorbance is 99% at normal incidence and remains very high over a wide …

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 …

Gold nanoparticles (GNPs) with controlled geometrical, optical, and surface chemical
