Nanomaterials has become one of the most prominent subjects in diverse fields of applications. Nanomaterials have emerged as one of the most promising things in different fields ranging from biomedical to pharmaceutical. The word nanomaterial originated from the Latin word 'Nanos' which means very small. Hence nanomaterials are particles of extremely small dimensions in the range of nanoscale. Nanotechnology has just added to the number of creative items in different building disciplines due to their remarkable and compensating substance, physical, and mechanical properties. One famous utilization of nanomaterials is nanotubes. Carbon nanotubes (CNT) are one of an illuminative model for the capability of nanotechnology. The elasticity of high carbon steel is around 1.2 GPa however the rigidity of carbon nanotubes (CNT) is 63 GPa. Likewise they are known to be perhaps the most grounded material having been created by nanotechnology up until this point. 1.1) WHAT ARE NANOMATERIALS? Nanomaterials can be seen as the building blocks or cornerstones of nanotechnology. Nanomaterials are defined as substances having at least one dimension in nanoscale i.e. less than approximately 100 nanometers. These materials play an important role because of the presence of unique magnetic, electrical ,optical and many other such properties at such a small scale. Many properties are seen to emerge at nanoscale range. Hence , Nanomaterials deal with substances in the range of 1-100 nm. 1.2) HISTORY The history of Nanomaterials started all after the big bang when formation of nanostructures occurred in the early meteorites. Many different nanostructures were identified after that such as sea shells. The Scientific approach of nanomaterials started however was developed much later. Michael Faraday's study on colloidal gold particles is one of such scientific reports known. Besides this , It has been more than 70 years of investigation on nanostructured catalysts. Today nanophase building extends in a quickly developing number of basic and practical materials, both inorganic and natural, permitting control of mechanical, reactant, electric, attractive, optical and electronic capacities. The creation of nanophase or group amassed materials is generally founded on the formation of isolated little bunches which at that point are melded into a mass like material or on their installation into minimized fluid or strong network materials.
