The German Environment Agency evaluates and reviews the aspects of nanotechnology relevant to the environment. What is nanotechnology? What opportunities and risks does it hold?

Nanotechnology involves research and development, production and processing of structures and materials on a nanometre scale. Nanotechnology deals with the production and application of processes and materials composed of structurally definable particles on a scale of about 100 nanometres (1 nm = 10-9 m) or less in at least one dimension.
