Is this "nanotechnology?
The NanoBreeze Car Air Purifier from NanoTwin Technologies uses
photocatalytic nanotechnology to clean and purify the air inside the
passenger compartment of any motor vehicle.
... Nanotechnology is the design, manufacture or control of single molecules and atoms to perform the duties of a machine. The NanoBreeze Car Air Purifier uses crystalline molecules of titanium dioxide TiO2 as a molecular machine. TiO2 is a semiconductor charged by UVA photons to drive oxidation and reduction reactions on the catalyst surface. The reactions convert organic pollutants to carbon dioxide and water. The process is known as oxidation by photocatalysis, from combining the Greek words for light and dissolve. Even the American Lung Association reports that photocatalytic nanotechnology is capable of rapidly destroying toxic components of tobacco smoke such as formaldehyde, acrolein, and benzene. More
