A novel method of preparing thiol-derivatised nanoparticles of gold, platinum and silver forming superstructures

Abstract

Thiol-derivatised nanoparticles of Au, Pt and Ag (diameter 1–10 nm) forming superstructures, are prepared by the acid-facilitated transfer of well characterized particles in a hydrosol to a toluene layer containing the thiol.
