Treating Metal Surfaces to Kill Bacteria

Bacterial pathogens can live on surfaces for days. What if frequentlytouched surfaces such as doorknobs could instantly kill them off Purdue University engineers have created a laser treatment method that could potentially turn any metal surface into a rapid bacteria killer just by giving the metals surface a different texture. In a study published in the journal Advanced Materials Interfaces, the researchers demonstrated that this technique allows the surface of copper to immediately kill off superb
