Copper’s Virus-Killing Powers Were Known Even to the Ancients

The SARS-CoV-2 virus endures for days on plastic or metal but disintegrates soon after landing on copper surfaces. Here’s why When researchers reported that the novel coronavirus causing the COVID-19 pandemic survives for days on glass and stainless steel but dies within hours after landing on copper, the only thing that surprised Bill Keevil was…

Copper kills corona viruses and bacteria but health experts are not informed

In 1832, 1849, and 1852, 200 employees from a copper smelter in Paris were unaffected by the cholera outbreaks, and this caught the attention of physician Victor Burq. 500 employees, who worked in the same area, were also spared from the cholera outbreak. This made Burq conclude that copper had given these people some kind…

Killing viruses with photacatalysis

A simple technique to make a common killing virus material significantly more effective is a breakthrough from the Rice University labs of Andrew Barron and Qilin Li who have taken nano particles that everyone’s been using for years and improved its performance without any real cost, said Barron, Rice’s Charles W. Duncan Jr.-Welch Professor of…
