TL;DR: Variations in reaction conditions and crystallographic analysis of gold nanorod have led to insight into the growth mechanism of these materials, and optical applications in sensing and imaging, which take advantage of the visible light absorption and scattering properties of the nanorods are discussed.

TL;DR: The seed-mediated approach to making gold nanorods in aqueous surfactant solutions has become tremendously popular in recent years, but unlike the use of strong chemical reductants to make spherical gold nanoparticles, the growth of gold Nanorods requires weak reducing conditions, leading to an unknown degree of gold reduction.

TL;DR: This surface enhanced Raman scattering (SERS) geometry offers large surface enhancements for molecules adsorbed onto planar substrates and could be quite useful for determining chemical information for poor Raman scatterers from assays on 2-D substrates.

TL;DR: Silver and gold nanorods with aspect ratios from 1 to 16 have been used as substrates for surface enhanced Raman spectroscopy (SERS) in colloidal solution and enhancement factors suggest that enhancement factors are a factor of 10-10(2) greater for substrates that have plasmon band overlap with the excitation source than for substrate whose plAsmon bands do not.
