The unique property of the steel-and copper-based material is its surface geometry etched with nanoscopic needles that pierce bacteria's cell wall, effectively killing it without detergents or antibiotics.
New antibiotic-resistant bacteria caused 1.27 million deaths worldwide in 2019. The material can combat these by rupturing the bacteria's cell membrane and depolarization without chemicals.
The material's design prevents the evolution of bacteria overdrive seen with antibiotics. Bacteria can't adapt to physical tearing as they can to chemicals, making the material highly effective.
The invention's antibacterial nature can benefit hospitals and kitchens, preventing serious illnesses. Tests with E. coli and staphylococcus showed successful elimination of gram-positive bacteria.
