Nanotechnology has been in use in a wide variety of scientific fields for about ten years. The term refers to the systematic analysis and manipulation of materials in a dimension that was once invisible even to microscopes: the nanometre range. There are one million nanometres in a millimetre, an order of magnitude that is difficult to imagine, let alone explain. Nevertheless, nanotechnology has incredible potential for modern science and technology.
