At such a small scale, nanotechnology is capable of interacting with biological and molecular systems uniquely, leading to beneficial applications in both medicine and science.

Brief History of the Field

The concept of nanotechnology was first articulated by physicist Richard Feynman in his 1959 lecture titled “There’s Plenty of Room at the Bottom.” In it, Feynman envisioned a future where scientists would manipulate individual atoms to create new materials. The term “nanotechnology” was later coined by Norio Taniguchi in 1974, and by the 1980s, tools like the Scanning Tunneling Microscope (STM) allowed scientists to actually see and manipulate atoms. This highlights the role of engineering in nanotechnology, aiming to create more effective nanoscale devices and coatings.

Advancements in tools like the STM have enabled the development of nanostructures, expanding the scope of technology significantly. Since then, nanotechnology has evolved rapidly, leading to breakthroughs in medicine, computing, and environmental science.
