Nanotechnology (nanotech) is technology based on materials, the single units of which, are smaller than 1000 nanometers, but usually smaller than 100 nm. At this scale, the technology is invisible to the unaided human eye; a sheet of newspaper is about 100,000 nanometers thick.
When materials have been manipulated to have one or more of their dimensions under 100 nanometres, they take on different properties – breaking their usual physical and chemical rules. For example, their strength, ability to conduct electricity and rate of reactivity increase massively; solids such as gold turn into liquids at room temperature, silver shows increased antimicrobial properties, inert materials like platinum and gold become catalysts, and stable materials like aluminium become combustible. The result is that we are given access to a more advanced level of.....
