A team of materials scientists from RMIT University and CSIRO has designed and fabricated a micro-nano copper structure and demonstrated its exceptional bactericidal efficacy against the common and deadly Staphylococcus aureus bacteria. “A standard copper surface will kill about 97% of golden staph within four hours,” said Professor Ma Qian, a researcher in the School of Engineering at RMIT University. “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. Professor Qian and colleagues used a special copper mould casting process to arrange copper and manganese atoms into specific formations. Robust bulk micro-nano hierarchical copper structures possessing exceptional bactericidal efficacy.
