Nanomaterials are the materials which has at least one spatial dimension in the size range of 1 to 100 nanometer. Nanomaterials can be created with various modulation dimensionalities. It can be individual nanostructure such as atomic clusters, quantum dots, nanocrystals, nanowires, and nanotubes, while collection of nanostructures involves arrays, assemblies, and superlattices of individual nanostructure. The physical and chemical properties of nanomaterials can significantly differ from atomic-molecular or the bulk materials of the same composition. Uniqueness of structural characteristics, response, dynamics, chemistry, and energetics of nanostructures constitutes the basis of nanoscience. There are several areas of concern in the nanomaterials market which are projected to be explored in the coming years, for instance, nanoparticles or nanocrystals of metals and semiconductors, nanotubes, nanowires, and nanobiological systems.
