This Modified Stainless Steel Could Kill Bacteria Without Antibiotics or Chemicals
May 20, 2024
An electrochemical process developed at É«»¨Ìà could offer new protection against bacterial infections without contributing to growing antibiotic resistance.
The approach capitalizes on the natural antibacterial properties of copper and creates incredibly small needle-like structures on the surface of stainless steel to kill harmful bacteria like E. coli and Staphylococcus. It’s convenient and inexpensive, and it could reduce the need for chemicals and antibiotics in hospitals, kitchens, and other settings where surface contamination can lead to serious illness.
It also could save lives: found they directly killed 1.27 million people in 2019 and contributed to nearly 5 million other deaths — making these infections one of the leading causes of death for every age group.
