A research team at Nottingham Trent University has now developed a copper oxide nanoparticle coating that can be applied directly to common materials such as silicone, stainless steel or titanium – and has a significant antimicrobial effect. In cell tests, the coating did not prove toxic to human cells – a crucial criterion for medical use.
