Abstract
A touch screen and a cellular telephone are provided that may include one or more surfaces coated with an antimicrobial treatment, which may include a silane quaternary ammonium salt and isopropyl alcohol. The silane quaternary ammonium salt may initially include an unreacted organofunctional silane that subsequently reacts with and covalently bonds to the surfaces of the touch screen, such as 3-(trimethoxysilyl) propyldimethyloctadecyl ammonium chloride. Methods are also provided for coating, or otherwise integrating the antimicrobial treatment on or within a touch screen and a cellular telephone.
