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.
