1. A self-sanitizing article, comprising:

  • an electromagnetic radiation waveguide structure; and

    an outer surface region disposed proximate to the electromagnetic radiation waveguide structure,wherein the outer surface region has a selected electromagnetic radiation absorber portion and forms the exterior of at least one of an electronic display screen or an electronic touch screen,wherein the electromagnetic radiation waveguide structure is configured to flow selected electromagnetic radiation energy internally therethrough substantially parallel to the outer surface region, andwherein the selected electromagnetic radiation absorber portion is disposed relative to the waveguide structure so that it is coupled to and heated by the electromagnetic radiation energy flow to a positive temperature to heat-sanitize an exposed portion of the outer surface region.
