Gold has always been the one precious material people like best. One of these special uses of gold refers to what is called 'nano gold', 'colloidal gold' or 'gold nano particles', i.e. sub micrometer sized particles of gold dispersed in a fluid, usually water. Gold Nano particles have unique physical, chemical and biological properties such as inertia, stability, bio compatibility, low level of cytotoxic and others, cause significant medico biological potential of gold nano particles and utilized in high end applications such as organic photovoltaic, sensory probes, therapeutics, drug delivery, electron microscopy, electronic conductors and catalysis.Features:
