The term nanotechnology applies to materials, structures and technologies with one thing in common: the creation or presence of at least one spatial dimension smaller than a few hundred nanometers. This includes the production of nanoparticles and the creation of nanostructures, which in turn make it possible to produce products with new or improved properties. Examples include starting materials for textiles that absorb UV radiation, water-repellant surface coatings for the textile and automotive industries and coatings that are more scratch resistant.
