Abstract: Disclosed herein are embodiments of filtration systems and iron oxide nanowire-based filter meshes that can capture and inactivate pathogens in air. The filter meshes can include a porous lattice of iron metal and iron oxide nanowires radiating from the porous lattice of iron metal. The iron oxide nanowires radiating from the porous lattice of iron metal can be created by processing the filter mesh using the disclosed method. Pathogens can be inactivated by passing a sample containing the pathogens through the filter mesh and inactivating at least a portion of the pathogens as the sample passes through the filter mesh.
