New device traps, then zaps, airborne pathogens
In the midst of this year's particularly bad flu season, we're reminded just how many nasty little particles roam the air we breathe -- from bacteria and viruses to allergens and diesel exhaust particulates.
But a new device that recently protected immunocompromised mice from these particulates has the potential to be both effective and safe for human use as well, according to researchers behind a new study published in the journal Applied and Environmental Microbiology.
"Small particles are difficult to remove, and our device overcomes that barrier," says Pratim Biswas, who chairs the Department of Energy, Environmental & Chemical Engineering at Washington University. In fact, the device not only traps the particles, it even inactivates them -- and that includes bioterror agents, Biswas says.… Read more
