Abstract
Embodiments of the invention are directed to a method of forming a self-sanitizing structure. The method includes forming a body region that includes scattering elements in a host composite material. The body region further includes a contact surface that can be contacted by a person during an intended use of the self-sanitizing structure. The method further includes forming an energy source configured to generate electromagnetic radiation and direct the electromagnetic radiation through the body region to the contact surface. Forming the body region further includes configuring the body region to scatter the electromagnetic radiation and pass the scattered electromagnetic radiation through the body region 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.
