Abstract: Virus and microbe-killing, self-sterilizing resistive heated air filters and methods of making and using same methods. The air filter is includes laser-induced graphene (LIG), a porous conductive graphene foam formed through photothermal conversion of a polyimide film (or another source or source of polymer or other LIG precursor material) by a laser source. The LIG in the air filter can capture particulates and bacteria. The bacteria cannot proliferate even when submerged in culture medium. Through a periodic Joule-heating mechanism, the filter easily reaches greater than 300° C. This destroys any microorganisms including bacteria, along with molecules that can cause adverse biological reactions and diseases such as viruses, pyrogens, allergens, exotoxins, endotoxins, teichoic acids, mycotoxins, nucleic acids, and prions.
