Laser texturing technique makes metal surfaces bactericidal


Key points from article :

Laser treatment of metal surfaces can kill bacteria on it rapidly.

One-step laser texturing technique uses a laser to create nanoscale patterns on the metal's surface.

Produce a rugged texture increasing the surface area of the metal.

So there’s more surface area for bacteria to come in to contact with the metal surface.

Chances of even resistant bacteria such as MRSA rupturing on the spot are higher.

Potential technology that could reduce risks of growth of bacteria and biofilms on implants in future.

Research by Purdue University, published in the journal Advanced Materials Interfaces.

Only works on metals that have antibacterial properties such as copper
