Abstract: We report recent achievements in metal-enhanced fluorescence from our laboratory Several fluorophore systems have been studied on metal particle-coated surfaces and in colloid suspensions In particular, we describe a distance dependent enhancement on silver island films (SIFs), release of self-quenching of fluorescence near silver particles, and the applications of fluorescence enhancement near metalized surfaces to bioassays We discuss a number of methods for various shaped silver particle deposition on surfaces

Probing Single Molecules and Single Nanoparticles by Surface-Enhanced Raman Scattering
Shuming Nie,Steven R. Emory +1 more
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.

A study of the nucleation and growth processes in the synthesis of colloidal gold
TL;DR: In this paper, a preliminary survey with the electron microscope of various preparations of colloidal gold, a study was made of the process of nucleation and growth in gold colloids, and it was shown that nucleating agents may be identified with reducing agents which form a mixed polymer with chlorauric ion before the reduction to the nucleus takes place.
