Nanotechnology is already widely used, but some scientists are warning it could prove dangerous in future. Why? Chemistry - Atoms And Bonding - Learning Points. Nanomaterials take on very different properties to their larger particles. Some studies have suggested that particles become increasingl reactive and toxic as their size decreases. Some carbon nanotubes have been shown to have asbestos-like qualities. The potential and unknown dangers with nano particles has created much controversy in science. A Twig Context Film. Reinforce and extend the learning required by the curriculum. Twig’s context films show abstract concepts in action in the real world.
