Definition

A gold nanorod is defined as nanometer-sized gold particles that are rod shaped. These solid, cylindrical nanoparticles have uniform diameters ranging from a few nanometers to hundreds of nanometers, with aspect ratios (length/diameter) larger than 1 but typically smaller than 10. Owing to their unique physical properties, gold nanowires/nanorods have many attractive applications in several areas, such as in life science, electronic and electromechanical devices, sensors, and solar cells. In the field of nanomedicine, the typical sizes for gold nanorods were around tens of nanometers in diameters and hundreds of nanometers in lengths. The crystalline structures of these gold nanomaterials can be either polycrystals or single crystals with different orientations, depending on the growth methods and conditions.
