The self-sanitizing stylus comprises a body including a component retaining enclosure and longitudinal member. The longitudinal member has a body defined between a distal end with a touch tip disposed thereon, and a proximal end secured with an operative end of the component retaining enclosure. At least one ultraviolet radiation emitting device is disposed on the body. The component retaining enclosure includes a power source and switch connected between the power source, and the ultraviolet radiation emitting device, which when pressed establishes an electrical connection between the power source and the ultraviolet radiation emitting device, which emits UV radiation to disinfect the body or portion thereof. ## Claims ### Claim 1 A self-sanitizing stylus for use in combination with a touch screen device, the self-sanitizing stylus comprising a body defined by a component retaining enclosure, and a longitudinal member extending from the component retaining enclosure;
