Sprayable Copper Nanowire Coating Could Help Prevent Infections.
Jul 28 2022Reviewed by Bethan Davies A team of researchers from Ames National Laboratory, Iowa State University, and the University of Buffalo created an antibacterial spray that deposits a coating of copper nanowires on high-touch surfaces in public places.
Copper ion can penetrate the membrane of a virus and then insert itself into the RNA chain, and completely disable the virus from duplicating itself. Cui explained that their inspiration came from another project that they were working on: a copper ink developed for printing copper nanowires used in flexible electronic devices.
The surface must first be cleansed and disinfected before applying the reformulated copper ink solution. The optimal coating should be clear and thin. The ink may be diluted with distilled water or alcohol to render it sprayable, and it operates on plastic, glass, and stainless-steel surfaces. Cui said that this study was significant not just because of the pandemic but also because these nanowires can protect against a wide range of microorganisms.Jun Cui, Study Lead Researcher and Scientist, Department of Materials Science & Engineering, Iowa State University, Ames
