Nanomaterials and Nanostructures attract tremendous attention worldwide in recent research fields, including physics, chemists, material scientists and mechanical and electrical engineers. Nanotechnology referees to the development of devices, structures, and systems whose size varies from 1 to 100 nanometers (nm). The term nano, originated from the Greek with the meaning of dwarf, indicates physical dimensions that are in the range of one-billionth of a meter. Thus, one nm is approximately the length of two hydrogen atoms and 1000 nm is the mean dimension of a bacterium. Nanoscale structures permit the control of fundamental properties of materials without changing the materials chemical status, requiring knowledge drawn from a variety of scientific and engineering arenas.
