Is Nanotechnology New? Where Did It Come Form?
Nanoscale materials have been used for over a thousand years. For example, nanoscale gold was used in stained glass in Medieval Europe and nanotubes were found in blades of swords made in Damascus. However, ten centuries passed before high-powered microscopes were invented, allowing us to see things at the nanoscale and begin working with these materials. Nanotechnology as we now know it began more than 30 years ago, when tools to image and measure at the nanoscale became available. Around the turn of the century, government research managers in the United States and other countries observed that physicists, biologists, chemists, electrical engineers, optical engineers, and materials scientists were working on interconnected, multidisciplinary issues emerging at the nanoscale. In 2000, the U.S. National Nanotechnology Initiative (NNI) was created to help these researchers benefit from each other’s insights, accelerate technology development, and foster commercialization across disciplines.
