This Modified Stainless Steel Could Kill Bacteria Without Antibiotics or Chemicals
May 20, 2024 —

Postdoctoral scholar Anuja Tripathi examines a small sample of stainless steel after an electrochemical etching process she designed to create nano-scale needle-like structures on its surface. A second process deposits copper ions on the surface to create a dual antibacterial material.
Researchers etch nano-sized textures and add copper ions to create a naturally antibacterial material for hospitals and other shared settings.
