Nanotechnology is already widely used, but some scientists are warning it could prove dangerous in future. Why?
- Nanomaterials take on very different properties to their larger particles.
- Some studies have suggested that particles become increasingly reactive and toxic as their size decreases.
- Some carbon nanotubes have been shown to have asbestos-like qualities.
- The potential and unknown dangers with nanoparticles have created much controversy in science.
Nanotechnology is already being used in many products, from lighter tennis rackets, to smoother paints, to more absorbent cosmetics.
And the next generation of nanomaterials promises to take things further.
Carbon nanotubes, with their incredible strength and electrical conductivity, could transform everything from computer chips to medicine.
Some suggest that nanorobots could be ...
