What Is Nanotechnology?

Nanotechnology is the creation of useful materials, devices, and systems through the manipulation of matter with dimensions of 1-100 nanometers. One nanometer is a billionth of a meter which is equal to 7 atoms lined up. The human hair is approx. 80,000 nanometers thick.

Nanotechnology is being applied to almost every field imaginable, including environmental, electronics, magnetics, energy, optics, information technology, materials development, and biomedicine. Because of their small size, nanoscale devices can readily interact with biomolecules on both the surface and inside cells. By gaining access to so many areas of the body, they have the potential to detect disease and deliver treatment in ways unimagined before now.
During the last decade, however, developments in the areas of surface microscopy, silicon fabrication, biochemistry, physical chemistry, and computational engineering have converged to provide remarkable capabilities for understanding, fabricating and manipulating structures at the atomic level.
Research in nanoscience is exploding, both because of the intellectual allure of constructing matter and molecules one atom at a time, and because the new technical capabilities permit creation of materials and devices with significant societal impact. The rapid evolution of this new science and the opportunities for its application promise that nanotechnology will become one of the dominant technologies of the 21st century. Scientists have agreed, within the next 20 years Nanotechnology will have had an impact on every industry on the planet.
