Description
n chemical terms, nanoparticles have different properties from their "big brothers and sisters": they have a large surface area in relation to their tiny mass and at the same time a small number of atoms. This can produce quantum effects that lead to altered material properties. Ceramics made of nanomaterials can suddenly become bendy, for instance, or a gold nugget is gold-coloured while a nanosliver of it is reddish. Up to now, very little research has been carried out on the effects of these altered properties on living organisms. Only recently, a study caused quite a stir by suggesting that nanoparticles like titanium oxide in toothpaste or sun cream have a similar effect on the human lung as asbestos.
