We quantitatively studied, using X-ray photoelectron spectroscopy (XPS), oxidation of
substrate-immobilized silver nanoparticles (Ag NPs) in a wide range of conditions, including …

Seed-mediated growth represents a simple and robust route to nanocrystals with well-
defined and controllable shapes or morphologies, and thus desired properties.[1] As a major …

We present a general route for the transfer of Au and Ag nanoparticles of different shapes
and sizes, from water into various organic solvents. The experimental conditions for each …

There has been a renewed interest in surface-enhanced Raman scattering (SERS) after the
demonstration of singlemolecule detection with substrates made of silver nanoparticles.[1, 2] …

Hybrid colloidal nanocomposites comprising polystyrene beads and plasmonic gold
nanostars are reported as multifunctional optical nanoprobes. Such self-assembled …

This study involves two aspects of our investigations of plasmonics-active systems:(i)
theoretical and simulation studies and (ii) experimental fabrication of plasmonics-active …

The progress of surface-enhanced Raman scattering (SERS) microscopy and spectroscopy
on individual nanostructured materials has been reviewed in this feature article. After a brief …

We present a simple, fast, and single-step approach for fabricating hybrid semiconductor-
metal nanoentities through liquid-assisted ultrafast (∼ 50 fs, 1 kHz, 800 nm) laser ablation …

Gold–silica self-assembled nanostructures are reported as multiplex surface enhanced
Raman scattering (SERS) tags for bioimaging applications. These hybrid colloidal particles …

Nanoparticles of noble metals are typically plasmonic materials, but the pure metals have
high nonirradiative ohmic losses at optical frequencies, leading to large absorption and …
