ABSTRACT

Nanomaterials are usually classified on the basis of their dimensionality, morphology, composition, uniformity, and agglomeration. The twenty-first century has witnessed a tremendous upsurge in the field of Nanomaterials and Nanotechnology. Nanotechnology is a broad interdisciplinary field, which requires expertise in physics, chemistry, materials science, biology, mechanical and electrical engineering, medicine, and their collective knowledge. Although some unique examples of nanomaterials or nanotechnology can be traced back for centuries, the excitement of nanotechnology is toward shrinking of the devices such as personal computer, laptop, smart phone, embedded processors. The progress in the field of nanotechnology has brought in breakthroughs in medicine and healthcare, nanoelectronics, energy, biotechnology, and information technology. Scientists have exploited the bottom-up nanotechnology of the nature and replicated a large number of examples including self-cleaning glasses, nanofabrics, nanomotors, nanobrushes, nanopaints, and hundreds of more developments by assembling and manipulating atoms, molecules, and solids.
