Metal Nanoparticles And Method Of Making Same

A method for making metal nanorods, the method comprising:

• combining a source of metal cations with at least one surfactant to form a mixture, wherein the metal cations are reduced and the metal nanorods are produced, and wherein the at least one surfactant comprises at least one gemini surfactant, optionally, the at least one gemini surfactant is a compound of the formula m-s-n, wherein m and n independently represent a hydrocarbon tail and s is a spacer, optionally, m and n are the same or different, optionally, m and/or n are saturated, optionally, m and n are less than 20, optionally, s is symmetric or asymmetric, optionally, s is saturated, optionally, s is butylene, optionally, wherein the length of the metal nanorods is proportional to s.
