Nanoparticle Masks and Goggles

Most people who know about nanoparticle masks probably wish they didn’t, since these micro-filtering protection devices first entered public awareness during the SARS outbreak of 2003.

These masks have been equipped with a filtration system that uses clusters of nanoparticles to remove microscopic biological pathogens from the air, and they were a huge success in Asian countries where the SARS epidemic hit hardest.

Now that the initial fear has faded, nanoparticle masks are once again on the margins of public attention. But the fact remains that they can perform an array of useful functions and may become indispensable in the event of a future disease outbreak.

How do nano-masks work? A molecularly enhanced particle coating is put on the mask’s filter; the nanoparticles in the coating have a tendency to cluster together enough to create a layer of ions that works together with trace amounts of chlorine to catch and eradicate any undesirable particles they encounter.
