Abstract
Embodiments of the invention are directed to a self-sanitizing structure that includes a body region having a contact surface that can be contacted by a person during an intended use of the self-sanitizing structure. The self-sanitizing structure further includes an energy source configured to generate electromagnetic radiation and direct the electromagnetic radiation through the body region to the contact surface. The body region is configured to scatter the electromagnetic radiation and pass the scattered electromagnetic radiation to the contact surface in a manner that maintains the scattered electromagnetic radiation that reaches the contact surface as sanitizing electromagnetic radiation. The sanitizing electromagnetic radiation is electromagnetic radiation that is at or above a minimum irradiance level that neutralizes infectious agents.
