Researchers at Australia’s RMIT University and the national science agency CSIRO, have developed a copper surface that kills bacteria more than 100 times faster and more effectively than standard copper and that could help combat the growing threat of antibiotic-resistant superbugs.
“A standard copper surface will kill about 97% of golden staph within four hours,” Ma Qian, one of the scientists involved in the study, said. “Incredibly, when we placed golden staph bacteria on our specially-designed copper surface, it destroyed more than 99.99% of the cells in just two minutes.”
According to Qian, the 120-times faster effectiveness rate was achieved without the assistance of any drug.
