Nanotechnology, which was first suggested by Richard Feynman in 1959 with the speech called ‘There’s plenty of room at the bottom’, represents a new frontier in research and development (R&D) across a broad spectrum of manpower and engineering efforts. Even according to its small size, the scope of nanotechnology is undeniably immense. Briefly, the study of structures and materials at the 'nano' scale, which is too small to be seen with the naked eye, and the development of these nanoscale structures, systems, devices and technologies is nanotechnology. A nanometer is one billionth of a metre. A hair is 50-100 thousand nanometers in size. A paper thickness is about 75,000 nanometers, and the pinhead is also about 1 million nanometers wide.
