Nanotexturing Creates Bacteria-Killing Spikes on Stainless Steel Surfaces

By using an electrochemical etching process on a common stainless-steel alloy, researchers have created a nanotextured surface that kills bacteria while not harming mammalian cells. If additional research supports early test results, the process might be used to attack microbial contamination on implantable medical devices and on food processing equipment made with the metal.
