Classification: CPC B  C | IPC B  C

Claim 9:
10. A method of making a filter comprising LIG, wherein the method comprises the steps of:
(a) exposing a first side of a sheet comprising a LIG precursor material to a first laser source, wherein
(i) the exposing on the first side results in formation of LIG on the first side of the sheet, and
(ii) the LIG is derived from the LIG precursor material;

(b) treating the second side of the sheet, wherein
(i) the second side of the sheet is on the opposite side of the first side of the sheet,
(ii) the LIG on the first side of the sheet and the step of treating on the second side provide a porosity to the sheet such that the sheet is configured to allow a flow of air through the LIG from the first side to the second side,
(iii) at least some of the LIG precursor material on the first side of the sheet is not formed into LIG and is operable to support the LIG formed on the first side, and
(iv) the LIG filter is capable of capturing particles or molecules selected from a group consisting of viruses, airborne microorganisms, byproducts of microorganisms, microorganism-associated toxins, viruses, virus capsids, droplets of virus capsids, and combinations thereof; and

(c) decomposing the captured particles via Joule heating.
