Copper nanowire spray effectively destroys covid19 virus
, the group explains that people have taken advantage of copper’s antimicrobial properties since 2400 B.C. to treat and prevent infections and diseases. The metal has proven effective for inactivating viruses, bacteria, fungi, and yeasts when they are directly in contact with the metal.
The idea to develop the antimicrobial spray came from a different project Cui and his colleagues were working on. They were developing a copper ink designed for printing copper nanowires used in flexible electronic devices. Cui explained that the first step is for the surface to be cleaned and disinfected. Once this is done, the reformulated copper ink solution can be applied. The ideal coating should be thin enough to be transparent. The ink can be diluted with water or alcohol to make it sprayable, and it works on plastic, glass, and stainless-steel surfaces.
