Unconventional Chain‐Growth Mode in the Assembly of Colloidal Gold Nanoparticles

Abstract

One-dimensional assembly of gold nanoparticles (see picture)is achieved by a sphere-to-cylinder transformation of polymer shells. A large amount of monomers remains after the assembly, which is characteristic of the chain-growth “polymerization”. Single-line chains can be converted to double-line chains, thus substantiating the unique role of the polymer shell.
