SYNTESIS OF NANOMATERIALS BY PHYSICAL AND CHEMICAL METHODS

Over the past decade, nanomaterials have been the subject of enormous interest. These materials, notable for their extremely small feature size, have the potential for wide-ranging industrial, biomedical, and electronic applications. Because of recent improvement in technologies to see and manipulate these materials, the nanomaterials field has seen a huge increase in funding from private enterprises and government, and academic researchers within the field have formed many partnerships. This paper describes the various techniques for synthesis of nanomaterials. There are basically two broad areas of synthesis for nanomaterials, the Top up approach and Bottom down approach. The first one holds many physical approaches, which are now in use for the fabrication and commercial production of nano materials. The chemical process offer over other methods is good chemical homogeneity, as chemical synthesis offers mixing at molecular level.
