Deterministic aperiodic arrays of metal nanoparticles for surface-enhanced Raman scattering (SERS)

TL;DR: The ability to rigorously design lithographically fabricated DA arrays of metal nanoparticles enables the optimization and control of highly localized plasmonic fields for a variety of chip-scale devices, such as more reproducible SERS substrates, label-free bio-sensors and non-linear elements for nano-plasmonics.

Probing Single Molecules and Single Nanoparticles by Surface-Enhanced Raman Scattering

TL;DR: In this article, surface-enhanced Raman scattering was used to detect single molecules and single nanoparticles at room temperature with the use of surface enhanced Raman, and the intrinsic Raman enhancement factors were on the order of 10 14 to 10 15, much larger than the ensemble-averaged values derived from conventional measurements.

Adsorption and surface-enhanced Raman of dyes on silver and gold sols

TL;DR: Several negatively charged dyes were investigated for their possible adsorption on the surface of colloidal particles and those dyes that were found to adsorb on the particles were then checked for surface enhancement of Raman scattering.
