Nano-scale Patterns Increase The Oligodynamic Effect of Copper

Researchers and engineers at Purdue University have demonstrated that a laser treatment technique can be used to alter the surface of copper, increasing the antimicrobial properties so that it is able to "immediately kill of super-bugs such as MRSA."
Assistant Professor at Purdue Rahim Rahimi stated: “We developed a one-step laser-texturing technique that effectively enhances the bacteria-killing properties of copper’s surface.”
By creating nanoscale patterns on the copper's surface, it is possible to increase the surface area, making it more likely that bacteria will come into contact with the copper and rupture on the spot.
The researches believe that the method could be incorporated into existing medical device manufacturing processes, as it is relatively simple and easily scalable.
