Gold nanorods: Synthesis, characterization and applications

Abstract

This article provides an overview of current research into the synthesis and properties of gold nanorods. Interest in rod-shaped nanoparticles stems from their unique optical properties, which can be approximated by Mie-Gans theory. We begin by outlining briefly the origin of the shape-dependent optical properties of rods. The different synthetic strategies that have been developed to achieve decent yields and sample monodispersity are then described, and the methods used for physical characterization as well as results of inorganic structure studies follow. Some of the most innovative research dealing with surface modification and chemical reactivity of gold nanorods is highlighted, togethe..
