The new metal also kills the H1N1 influenza A virus (the virus strain behind swine flu) and E. coli bacteria.

A team at the University of Hong Kong have developed the first anti-pathogen stainless steel that kills infectious viruses, including COVID-19, on its surface.

The metal also kills the H1N1 influenza A virus — the virus strain behind swine flu — and E. coli bacteria. However, the researchers found that traditional stainless steel does not have antibacterial or antiviral properties. On the contrary, the COVID-19 virus shows "strong stability" on the surface of conventional stainless steel, with infectious virus detected even after two days, according to the University of Hong Kong.
