According to Stephanie Yang on WSJ, copper is used in everything from construction to electrical wiring, but it also has antimicrobial properties that kill 99.9% of bacteria on its surface within two hours, according to the Environmental Protection Agency. That makes it a potential weapon for combating the spread of infections in hospitals and public areas.
More than 150 social insurance and different offices have introduced antimicrobial copper composite surfaces fabricated in the U.S. since 2011, as indicated by the Copper Development Association. Items range from copper trucks and sinks to entryway handles.
