Phys.org  December 9, 2021 SARS-CoV-2 exhibits strong stability on conventional stainless steel (SS) surface, with infectious virus detected even after two days. Researchers in Hong Kong investigated the stabilities of SARS-CoV-2, H1N1 influenza A virus (H1N1), and Escherichia coli (E.coli) on the surfaces of Cu-contained (SS), pure Cu, Ag-contained SS, and pure Ag. They found that pure Ag and Ag-contained SS surfaces do not display apparent inhibitory effects on SARS-CoV-2 and H1N1. In comparison, both pure Cu and Cu-contained SS with a high Cu content exhibit significant antiviral properties. Anti-pathogen SS with 20 wt% Cu can distinctly reduce 99.75% and […]
