Nanotechnology refers to a wide range of technologies and materials that create, manipulate, or use particles that are extremely small and have dimensions roughly between 1 and 100 nanometres (nm). A nanometre is 1 billionth of a metre. Most research and studies have concentrated on nanomaterials with at least one dimension of less than 100 nm.
Nanotechnology is a field that is quickly changing both in terms of how we use it, and in our understanding of it. The best approach to take is the precautionary principle - the need to take prudent action in the face of potentially serious risk, without waiting for the completion of further scientific research.
