What Is Nanotechnology and is it possible?
Nanotechnology, a branch of science and engineering, is concerned with nanoscale, or extremely small sizes, materials and devices. The Greek word "nanos," which means "dwarf," is where the word "nano" originates. A nanometer (nm) is one billionth of a meter in size, which is extremely small. A human hair has a diameter of roughly 100,000 nanometers, for comparison. As scientists and engineers have found new ways to handle and control materials at the nanoscale, the area of nanotechnology, which has its beginnings in the late 20th century, has swiftly expanded since...
