Nanotechnology is the process of constructing devices from single atoms and molecules. Although it is relatively new to modern science, it is a rapidly growing industry, and advances are continually being made. Sandia National Laboratories is conducting several projects on various aspects of nanotechnology. Its Web site is a good starting point to learn the basics of nanotechnology and see videos of the work being conducted. For children, Exploring the Nanoworld has many descriptive QuickTime movies and even a downloadable booklet that shows how LEGO's can be used to demonstrate nanotechnology principles. The Study of Nanotechnology has some good information for college-bound students interested in specializing in the subject. Nanotech Planet offers business news about companies using the technology, while breakthroughs and innovations in the field are discussed at Nanodot. The Nanomedicine Art Gallery shows many artist renderings of what nanorobots might look like when used as medical devices within the human body. A very interesting article about a recent advancement in physical atomic arrangement is given at The Magic of Nanoclusters. Another newsworthy site about nanotubes from Berkeley Laboratory provides an in-depth explanation of this thriving, new development within the nanotechnology industry.
