Definition and Uses of Nanotechnology
Nanotechnology. Sounds really Sci-Fi, right? Well, it is and isn't. Nanotechnology is science, engineering, and technology conducted at the nanoscale. The nanoscale is approximately one to one hundred nanometers.
The ideas and gist of these studies started because of a talk given by physicist Richard Feynman called “There’s Plenty of Room at the Bottom”. He gave this talk at an American Physical Society meeting in the California Institute of Technology (CalTech) in late December of 1959, far before the term Nanotechnology was used.
What qualifies as “nanotechnology” today is simple research and development that is happening in laboratories all over the world. “Nanotechnology” products that are on the market today are mostly slowly improved products (using evolutionary nanotechnology) where some form of nanotechnology enabled material (such as carbon nanotubes, nanocomposite structures or nanoparticles of a particular substance) or nanotechnology process (nanopatterning or quantum dots for medical imaging) is used in the manufacturing process. In their ongoing quest to improve existing products by creating smaller components and better performance materials, all at a lower cost, the number of companies that will manufacture “nanoproducts” (by this term) will grow very fast and soon make up the most of all companies
