Gold is used as nano Particles in form of colloidal gold, magnetic nanogold Particles, nanogold sphere, nanoshell, nanorods, gold cluster. Colloidal gold is used in form of gold clusters called nanogold. Nanogold is a 1.4nm gold cluster. Nanogold is actually a coordination compound containing a gold core covalently linked to surface organic groups.The colloidal gold is used to treat experimentally-induced arthritis in rat models. Gold nanoshells are spherical particles with diameters typically ranging in size from 10 to 200 nm. They are composed of a dielectric core covered by a thin gold shell. As novel nanostructures, they possess a remarkable set of optical, chemical and physical properties, which make them ideal candidates for enhancing cancer detection, cancer treatment, cellular imaging and medical biosensing.
