Everyday Objects Reinvented Using Copper
Copper objects that eliminate bacteriaNumerous scientific studies and experiments have demonstrated copper’s effectiveness againstbacteria in a hospital environment. An environment kitted out with copper surfaces can reduce the risk of catching a healthcare-associated infection by greater than 40%1. These discoveries can now beapplied to everyday objects. The objective? To permanently eliminate bacteria and germs thatcolonise objects handled on a daily basis and prevent infections such as flu or gastroenteritis. In this area, objects such as the humble computer keyboard are amongst the leading sources ofcontamination. According to a study conducted by Which? Computing magazine, a keyboard cancontain 150 times more bacteria than the limit recommended by British health authorities. Thanks to the red metal’s antimicrobial properties, a keyboard made using copper is, to a certain extent, “self disinfecting”, permanently eliminating bacteria. Between 90% and 100% of the bacteria present on acopper surface are eradicated in just a few minutes. This could have more than a negligible effect onusers: in fact, it is estimated that 80% of infections are transmitted by contact with contaminated surfaces. Copper could soon be used for the manufacture of other objects particularly prone to bacterial contamination. For example, a study conducted in the United States has shown that supermarket trolleys are veritable breeding grounds for bacteria: traces of faecal bacteria can be found on 72% oftrolley handles. Mobile phones are also affected: according to a study carried out in the United Kingdom, 92% of mobiles carry bacteria, of which 16% carry Escherichia coli bacteria, which are often responsible for upset stomachs. This offers even more potential future uses for copper!
