Nano-Science and Nano -technology involve studying and working with matter on an ultra-small scale. One nanometer is one-millionth of a millimeter and a single human hair is around 80, 000 nanometres in width. The technology stretches across the whole spectrum of science, touching medicine, physics, engineering and chemistry. Scientists, for example, are looking at whether nanotechnology could be used to improve the delivery of cancer fighting drugs and are ...
