Nanotechnology – a science under discussion
For many years, nanotechnology has been considered a science of unlimited possibilities. These tiny particles and structures enable materials with exceptional properties to be produced. They can, for example, help to make plastics both lighter and more stable, or to make high-gloss coatings scratch-proof. They can also be used to develop new medicines. But, at the same time, there is some doubt. Critics see a risk that nanoparticles will get into human cells or the environment – and warn that there has not yet been sufficient research into this technology.
