[nanoPost] Anti-biohazard nanocoatings

Company USA

Nanoparticle coatings that can be used in protection of surfaces from the hazards associated with chemical and biological warfare agents.

The product developed to mitigate against the threat of a dirty bomb by mitigating the spread of radioactive material from wind, rain and smearable transport. Smearable and airborne radioactive, chemical and biological contaminants represent a particularly severe threat to emergency workers and civilians in the broad area of a radionuclide dispersion event.

In the case of a dirty bomb in particular, while radiation exposure may only threaten those closest to ground zero, contamination threats exist – according to some simulations – across a several mile radius from the detonation site, due to the spread of radionuclides by contact and wind. The product can be quickly applied over a wide area by brush, spray or roll to immediately lock-down contaminants.

In addition to the airborne and smearable contamination issue, absorbent surfaces, like soil and asphalt, pose a specific decontamination challenge due to their ability to absorb some contaminants very rapidly. Building materials, such as soil, concrete, wood, are known to quickly absorb ionic radionuclides deep into their substructure, thus complicating non-destructive decontamination efforts. The product, if applied quickly, can trap these contaminants in the coating layer, such that the decontamination effort - to return the area back to "background" condition - can be deferred until a strategically opportune time following emergency response.
