| 説明 | Brass door knobs, handles and handrails should be brought back into common use in public places to help combat superbugs, according to scientists. Researchers have discovered that copper and alloys made from the metal, including brass, can prevent antibiotic resistance in bacteria from spreading.Plastic and stainless steel surfaces, which are now widely used in hospitals and public settings, allow bacteria to survive and spread when people touch them. Until relatively recently brass was a relatively commonly used surface. On stainless steel surfaces these bacteria can survive for weeks, but on copper surfaces they die within minutes.“Part of the process DNA from bacteria is also destroyed just as rapidly on the copper, so you cannot get gene transfer on the surface. |
