The evolution of nanotechnology can be traced back to Richard Feynman's famous lecture, "There's Plenty of Room at the Bottom," in 1959. The term "nanotechnology" was later coined by Norio Taniguchi in 1974. The development of the scanning tunneling microscope (STM) and the atomic force microscope (AFM) in the 1980s allowed scientists to see and manipulate individual atoms, significantly advancing the field.
