Abstract
A breathing system for removing harmful contaminants, such as microbes and volatile organic compounds, is provided. The breathing system includes a face mask, an inhalation limb, and a plasmonic device. As a contaminated gas flows through an internal chamber of the plasmonic device, the contaminates are oxidized. Specifically, the internal chamber includes a source of photons spaced apart from the nanostructure. The nanostructure is coated in a plasmonic layer, including noble metal nanoparticles. The plasmonic layer is protected from oxidation through a photocatalyst layer disposed thereon.
