Abstract
The present invention relates to a nanocrystalline photocatalyst active upon visible light irradiation, with a high degree of dispersion, stable in the form of a transparent colloidal solution in an aqueous environment, containing nanocrystals of titanium dioxide (TiO) surface-modified via direct chemisorption of organic compounds. The present invention in turn relates to a method of producing the material as well as its use as a photosterilizer, photobacteriocide, photomycocide, and/or photocatalyst, in particular for the sterilization of glass surfaces, transparent plastics and transparent materials, in particular contact lenses, medical catheters, glass and plastic conduits as well as other surfaces, whose sterilization is desirable and/or required.
