Claim 17:
18. A LIG film that comprises LIG and a LIG precursor material, wherein
(a) the LIG film is a filter configured for filtering air by capturing particles in the air, wherein the LIG is a two-side LIG structure, wherein
(i) the two-sided LIG structure has the LIG on both sides of the LIG film, where the LIG on both sides of the LIG film are adjacent to one another such that air can be filtered through the LIG of the two-sided LIG structure, and
(ii) the two-sided LIG structure has LIG precursor material on both sides of the LIG film, wherein the LIG precursor material is a support of the LIG on both sides of the LIG film;

(b) the captured particles are selected from a group consisting of virus particles, airborne microorganisms, byproducts of microorganisms, microorganism-associated toxins, and combinations thereof;
(c) the LIG film is capable of generating heat when a voltage is applied across the LIG; and
(d) the generated heat is capable of killing or decomposing the particles.
