Treating Metal Surfaces to Kill Bacteria

Bacterial pathogens can live on surfaces for days. What if frequently-touched 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 metal’s 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 superbugs such as MRSA.
