Device detects, traps and deactivates airborne viruses and bacteria
An environmental engineer at Washington University in St. Louis with his doctoral student has patented a device for trapping and deactivating microbial particles. The work is promising in the war on terrorism for deactivating airborne bioagents and bioweapons such as the smallpox virus, anthrax and ricin, and also in routine indoor air ventilation applications such as in buildings and aircraft cabins. On the walls of the device, Biswas has coated nanoparticles that catalyze the oxidation. These nanoparticles are "smart" objects that are turned "on" and "off" by irradiation.
