The study of the surface plasmons of noble metals has emerged as one of the most rapidly
growing and dynamic topics in nanoscience. Key advances in the synthesis of noble metal …

Au nanoparticles with diameters ranging between 15 and 170 nm have been synthesised in
aqueous solution using a seed-mediated growth method, employing hydroxylamine …

The review describes electrochemical applications of tip-enhanced Raman spectroscopy
(TERS). These applications combine the merits of both scanning probe microscopy (SPM) …

We demonstrate that second-harmonic generation (SHG) from arrays of noncentrosymmetric
T-shaped gold nanodimers with a nanogap arises from asymmetry in the local fundamental …

In this paper, we develop a classical electrodynamic theory to study the optical nonlinearities
of metallic nanoparticles. The quasi free electrons inside the metal are approximated as a …

Attainment of spatial resolutions far below diffraction limits by means of optical methods
constitutes a challenging task. Here, we design nonlinear nanorulers that are capable of …

We consider the optical properties of a periodic array of silver spherical particles with
diameters of a few hundred nanometers on top of a thin Ag film. Maxwell's equations are …

To our knowledge, the present work reports the first in vivo observation of chlorophyll a
fluorescence quenching induced by gold nanoparticles. Laser-induced fluorescence …

Nanoisland films prepared by annealing thin gold films at high temperatures were imaged
using scanning electron microscopy (SEM) and atomic force microscopy, and optically …

A molecular-scale understanding of electrolyte/electrode interfaces has long been a
challenging issue in electrochemistry. Spectroscopic tools with high spatial resolution are …
