An innovative filter made of electrified graphene foam can kill airborne microbes and their byproducts.
Ideal for use in hospital settings, the team at Rice University created the graphene-based filter using the group’s earlier developed, unique laser-induced graphene. When exposed to a current, the flexible foam graphene will heat to up to 662°F, which is more than hot enough to kill all airborne pathogens, from bacteria to prions. The heat can be applied as needed, killing the captured pathogens in seconds with a nominal amount of power.
According to Rice lab chemist James Tour, “It’s been predicted that by the year 2050, 10 million people per year will die of drug-resistant bacteria. The world has long needed some approach to mitigate the airborne transfer of pathogens and their related deleterious products. This LIG air filter could be an important piece in that defense.”
