Abstract

original image

Gold nanocrystals can crystallize in supracrystals with a low size distribution. These mesostructures show different morphologies. Experiments and supporting simulations presented by Marie-Paule Pileni and co-workers, on page 2693, show that the solvent in which the Au nanocrystals are dispersed governs the final morphology of the nanocrystal assemblies in supracrystals. Either well-defined shapes are grown in solution, or a layer-by-layer growth on a substrate, with the formation of well defined films characterized by their plastic deformation, is observed.
