Nanotexturing on stainless steel creates bacteria-killing spikes

December 21, 2017

By using an electrochemical etching process on a common stainless steel alloy, researchers have created a nanotextured surface that kills bacteria, according to an article on the Infection Control Today website.

The researchers believe tiny spikes and other nano-protrusions created on the surface puncture bacterial membranes to kill the bugs. 

Beyond the anti-bacterial effects, the nano-texturing also appears to improve corrosion resistance. 

The research was reported Dec. 12, 2017, in the journal ACS Biomaterials Science & Engineering by researchers at the Georgia Institute of Technology.
