The concept of nanotechnology was primarily attributed to a lecture given by the renowned Nobel laureate scientist Richard P. Feynman in 1959, which was published in 1960 (Feynman in A Lecture in engineering science. California Institute of Technology, 1960) under the title “There is Plenty of Room at the Bottom.” In this famous lecture, the great scientist uttered these famous words: “The principles of physics, as far as I can see, do not speak against the possibility of maneuvering things atom by atom. It is not an attempt to violate any laws; it is something, in principle, that can be done, but in practice, it has not been done because we are too big.”
