Nanoparticles have a very large surface area compared with their volume, so they are often able to react very quickly and are used in catalysts because of this.
In addition to new cosmetics such as sun screens and deodorants, nanoscience may lead to the development of:
New catalysts
New coatings
New computers
Stronger and lighter building materials
Sensors that detect individual substances in tiny amounts
Polymers
