Nano Technology
Nanotech which is the short form of nanotechnology is the use of matter on an atomic, molecular, supra molecular scale for industrial purposes. Two main approaches are used in nanotechnology. In the “Bottom-up” approach, materials and devices are built from molecular components which assemble themselves chemically by principles of molecular recognition. In the “top-down” approach, nano-objects are constructed from larger entities without atomic-level control.
The American physicist and Nobel Price laureate Richard Feynman introduced the concept of nanotechnology in 1959. During the annual meeting presented a lecture entitled “There’s plenty of Room at the Bottom” at the California Institute of Technology (Caltech)
Nanotechnology is used to manufacture structures in coal, silicon, inorganic materials, metals, and semiconductors that do not work with humidity. It is based on biological systems present in an aqueous environment. Is it a small solution to big problems? Potential disadvantages include economic disruption and possible threats to security, privacy, health, and the environment. But it has many cancer cells, faster microprocessors that consume less energy, batteries that last 10 times longer, or solar panels that yield twice as much energy. Nanotechnology offers the potential for new and faster kinds of computers, more efficient power sources, and life-saving medical treatments.
