Nanotechnology involves the understanding, manipulation, and control of matter at dimensions of roughly 1 to 100 nanometers. Nanotechnology encompasses science, engineering and technology and involves imaging, measuring, modeling, and manipulating matter at the nanoscale. The development of unique nanoscale structures has the potential to revolutionize industry, including electronics, medicine, and consumer products.
Examples of materials developed with nanotechnology include the following engineered nanomaterials:
- Carbon buckyballs or fullerenes;
- Carbon nanotubes;
- Metal oxide nanoparticles (e.g., titanium dioxide); and
- Quantum dots, which are nanoscale semiconductor materials (e.g., cadmium selenide).
Although the development and application of nanotechnology is primarily still in the research phase, some engineered nanomaterials are produced and used in commercial applications today. Examples of products that are produced currently using nanotechnologies include:
- Sunscreens and cosmetics;
- Longer-lasting tennis balls and light-weight, stronger tennis racquets;
- Stain-free clothing and mattresses;
- Polymer films used in displays for laptops, cell phones, digital cameras;
- Coatings for easier cleaning glass;
- Bumpers and catalytic converters on cars; and
- Protective and glare-reducing coatings for eyeglasses and cars.
National Institute of Standards and Technology (NIST), Department of Commerce (DOC). NIST, a non-regulatory agency created to promote U.S. industrial innovation and competitiveness, enables science and industry by developing measurement methods, instrumentation, standards, and data to support all phases of nanotechnology development. NIST's Center for Nanoscale Science and Technology operates the Nanofab, a shared-use facility providing economical access to state-of-the-art nanotechnology-measurement tools and nanofabrication, and a research program. The NIST nanotechnology webpage contains information on nanotechnology activities, news, developments and accomplishments, including the work of the Center.
