Nanotechnology, abbreviated to "nanotechnology," is the study of the control of matter at the atomic and molecular scales. Nanoscience and nanotechnology represent a recent and revolutionary development in the field of science and engineering, which is evolving at a very rapid pace.[1,2] It is driven by the desire to fabricate materials with new and improved properties that are likely to have impacting virtually all areas of science and engineering. physical and chemical sciences, biological sciences and health sciences. The word 'nano' comes from the Greek word 'nanos', meaning dwarf or extremely small and mathematically a nanometer is one billionth of a meter or 10-9 m. Particles whose sizes fall within the size range 1-100 nm are called nanoparticles, regardless of whether they are dispersed in a gaseous, liquid or solid medium. Nanotechnology generally deals with structures 100 nanometers or less in size and involves the development of materials or devices within those dimensions. Nanotechnology is very diverse and ranges from extensions of conventional device physics, to completely new approaches based on molecular self-assembly, to the development of new materials with...
