Richard Feynman, the American physicist who specializes in theoretical quantum and won the Nobel Prize in 1965, in his famous speech "There is a lot of space down there" examined the immature dimension of materials and drew the attention of thinkers around the world to this science and the ability to produce materials, tools. And described new systems by taking control of size at the molecular and atomic levels. As long as it covers the whole world today. Today, many advances have been made in the field of nanotechnology to refine the definition of this knowledge. Simply put, nanotechnology in the world, from forty years ago until now, nanotechnology and the wide range of applications that have introduced this technology as an interdisciplinary and cross-sectoral field, can be applied to its applications in materials science, medicine and health, pharmacy, He mentioned electronics and computers, engineering, the environment, biotechnology, the defense industry, energy, agriculture and many other industries such as textiles, steel and electricity. Now this science and its dimensions can be considered beyond the present and it can be said that nanotechnology is not part of the future, but the whole future!
