Gold Nanorods - An Overview

Abstract

This article provides an overview of current research in structure, synthesis, properties, application of gold nanorods. Interest in rod- shaped nanoparticles steam of unique optical properties, 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. The most popular and successful method for creating high-quality gold nanorods is seed-mediated development. optical properties of gold nanorods, absorption spectrum of colloidal dispersion of gold nanorods, local field effect and sensing application, color of colloidal dispersion of gold nanorod, polarization dependent color and absorption in polymer gold. Gold nanorods are utilized in a range of applications including biosensing, photothermal therapy, bioassays, biomedical imaging, and drug delivery. All these properties make gold nanorod a good candidate for future nanoelectronics in this article, we will describe the preparation and characterization of gold nanorods.
