Abstract: A process for depositing an inorganic material on a substrate, the process comprising, providing a substrate having a surface, providing a precursor mixture comprising a metal sulfonate, and delivering the precursor mixture to the surface of the substrate, wherein the surface of the substrate is at a substrate temperature of above 450° C. and is sufficient to effect decomposition of the metal sulfonate. The inorganic material may include a metal or a metal oxide. The preferred metal sulfonate is metal triflate.

Abstract: The present invention presents a mixture comprising charge-stabilized metallic nanoparticles and a photosensitizer, a method for making such mixture, and a method of using such mixture for killing or preventing the growth of microbes.

Abstract: Computer devices (10) that are resistant to contamination by microbes are provided. The device (such as a keyboard (10), mouse or other computer device) is treated or manufactured with a photosensitizer compound that is activated by electromagnetic radiation (16) to provide an antimicrobial effect. One or more light sources (14; 19) may be utilized to activate the photosensitizer compound and these may be incorporated inside or outside of the computer device (10). A laptop computer in which the electro-magnetic radiation is provided by the display screen (30) so as to provide an antimicrobial effect to the keyboard (13) is described.
