UArk researchers create antimicrobial surface with silver nanowires

Researchers at the University of Arkansas have developed a new antimicrobial surface using silver nanowires. This surface combines the antibacterial properties of silver with a small electric current to kill bacteria and viruses effectively. Silver is known for its ability to eliminate harmful microorganisms. When combined with an electric current, the effect is even stronger, according to physicist Yong Wang, one of the lead researchers. In laboratory tests, this new technology successfully killed all E. coli bacteria on glass surfaces. The researchers created a network of silver nanowires that not only attacks germs but also conducts electricity across the surface. This system uses a low electric current that is not felt by touch, making it safe to use. A tiny solar cell could power the setup, making it efficient as well. This innovative surface could have many uses. It could be applied to door handles and countertops to keep them germ-free. It also has potential applications in medical and food facilities, as well as restaurant kitchens. Additionally, the technology could be used in cloth, serving as effective filters for ventilation systems or personal protective equipment like masks and gowns. The U of A is currently seeking patent protection and looking for companies interested in bringing this technology to market.
