Nanomaterials describe, in principle, materials of which a single unit is sized (in at least one dimension) between 1 to 1000 nanometres (10−9 meter) but usually is 1 to 100 nm (the usual definition of nanoscale).
The extinction of plants and animals can have devastating effects on the environment as well as on humans. An EU-funded project is exploring methods to conserve biodiversity in areas where species are threatened.
