Claim:
1. A method comprising: growing metal nanowires from a reaction solution including a metal salt and a reducing agent, wherein the growing includes: reacting a first portion of the metal salt and the reducing agent in the reaction solution for a first period of time, wherein the first portion of the metal salt is reduced and grows in both a radial direction and an axial direction to form a plurality of precursors of metal nanowires; and gradually adding a second portion of the metal salt over a second period of time while maintaining a substantially constant concentration of less than 0.1% w/w of the metal salt in the reaction solution, wherein the plurality of precursors of metal nanowires predominantly grow in the axial direction to form the metal nanowires.
