The team led by Professor Mingxin HUANG at the Department of Mechanical Engineering of the Faculty of Engineering of the University of Hong Kong (HKU), in collaboration with Professor Leo Lit Man POON's research team at the Centre for Immunity and Infection of the LKS Faculty of Medicine of HKU, has made significant breakthroughs in producing the first anti-COVID-19 stainless steel that kills the severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) on its surface. The anti-COVID-19 stainless steel can also inactivate the H1N1 virus and E.coli on its surface.
