Large-scale synthesis of silver nanowires...

A self-seeding process, involving reduction of AgNO3 with ethylene glycol at ~160°C, has been used to generate bicrystalline silver nanowires. The key to the success of this solution-phase approach is the use of a polymeric "coordination reagent" capable of controlling the growth rates of different faces of silver. Uniform nanowires could be routinely synthesized with diameters of ~60 nanometers and lengths up to ~50 micrometers (Y. Sun, Y. Xia, Adv. Mater. 2002, 14, 833-837).
