"Nanotechnology is being applied in a wide range of industrial and technological sectors, including food, information technology, energy, environment, security, textiles, and medicine, among others. Nanotechnology is the application of scientific knowledge to manipulate and control matter in the nanoscale (size range from approximately 1-100 nanometre (nm)) in order to make use of size and structure-dependent properties and phenomena, distinct from those associated with individual atoms, molecules or larger-scale materials. From a health and safety perspective, it is more typically nano materials--chemical substances or materials that are manufactured and used to exploit novel characteristics compared to the bulk material such as increased strength, chemical reactivity or conductivity--and not nano technology that's regulated and the subject of conventional risk assessment."
