Abstract

Abstract : Seeding-growth method for gold nanoparticles with a high level of size predictivity and a very low polydispersity. Abstract : We report a seed-mediated synthesis strategy to control the size of gold nanoparticles at the atomic scale in the 2–5 nm size range. Starting from 2 nm seeds, a regrowth in organic solvent with a designed amount of precursor can achieve in a predictive fashion a precise mean size with a 0.3 nm resolution. We show that these monodisperse nanoparticles assemble into a 2D hexagonal lattice over a distance that can span tens of micrometers.
