Copper is amazing- But only now does our research describe how copper and its alloys exhibit these impressive properties and the processes involved. The process involves the release of copper ions (electrically charged particles) when microbes, transferred by touching, sneezing or vomiting, land on the copper surface. The ions prevent cell respiration, punch holes in the bacterial cell membrane or disrupt the viral coat, and destroy the DNA and RNA inside. This latter property is important as it means that no mutation can occur – preventing the microbe from developing resistance to copper. Global concern is growing over antimicrobial resistance and the risk of death that it presents from common infections in even minor operations. Therefore, it is fortunate that copper alloys kill superbugs, including MRSA and those from the notorious ESKAPE group of pathogens – the leading cause of hospital-acquired infections.
