Nano In Brief
By Gina Miller June 11, 2003
Nanotechnology is an emerging science, meaning there are nanoscale products that have already been developed but there are potential future applications that would revolutionize the world that society lives in. Nanotechnology was first highlighted by physicist Richard Feynman in his 1959 talk at the California Institute of Technology. Feynman suggested that we begin to think about manipulating atoms \"we can arrange the atoms the way we want; the very atoms, all the way down! What would happen if we could arrange the atoms one by one the way we want them\". In 1986 MIT engineering graduate K. Eric Drexler published the book Engines Of Creation which described the unbelievable applications of nanotechnology and brought the topic to a controversial forefront.
Nanotechnology is a scale or size much in the way that micro technology is thought of. A nano meter is a thousand times smaller than a micro meter. Three to five atoms fit inside of one nanometer. A nanometer is so small that not just any microscope can be used to see and work at this level, but only special types of microscopes, called scanning probe microscopes. While nanotechnology is already being used in fabrics, sunscreen and other materials, Drexler\'s nanotechnology has the goal of being able to build with molecules to make systems of molecular machines.
Drexlerian nanotech suggests that with molecular machines it would be possible to build almost anything that could be imagined that the laws of physics allow. This would mean that molecules could be arranged into any pattern desired. Engineers would be able to design and build machines that would be every bit as intricate as the marvelous machinery of living cells. This would bring about invisible microscopic machines that could roam inside the human body to repair cells damaged by disease or aging.
