Copper is a powerful germ killer
In 2002 the U.S. Environmental Protection Agency was searching for a way to stop the spread of deadly diseases in hospitals. The EPA approved the registration of copper as antimicrobial, officially stating copper is capable of killing harmful, potentially deadly microbes. Since then a huge outpouring of research from universities, hospitals, and labs around the world proves that copper kills many viruses and bacteria rapidly on contact.
Hospitals are using copper to stop deadly diseases
Copper even kills antibiotic resistant bacteria such as MRSA. Hospitals have tested solid copper as a replacement for touch surfaces such as patient bed rails, tray tables, chair arms, doorknobs, faucets, etc. In hospitals tested, hospital-acquired infections dropped dramatically.
How does copper work?
Scientists have identified a number of ways copper can destroy bacteria and viruses. One is electrical. It is strongly suspected that when a bacterium comes in contact with a copper surface, a short circuiting of the current in the cell membrane occurs. This weakens the membrane and creates holes in it. In other words, copper zaps the germ.
These are some of the scientists, among others, whose researched helped inspire the idea for CopperZap
Professor Bill Keevil
Director of the Environmental Healthcare Unit in the School of Biological Sciences, and his team at the University of Southampton, examine survival rates of deposits of pathogens (including MRSA, E Coli, Listeria monocytogenes, Influenza A(H1N1), Aspergillus niger, Clostridium difficile) on stainless steel (the metal most commonly used in healthcare and food processing institutions) and on a range of copper alloys.
Dr. Christopher Rensing
While at the University of Arizona, Dr. Rensing demonstrated that copper starts killing microbes in less that a minute after direct contact with a copper surface. He coined the term “contact killing” for the effect of copper on microbes.
Dr. Gregor Grass
Dr. Gregor Grass, Institut für Mikrobiologie der Bundeswehr. General research interests are in microbe-metal interactions. One focus of his research is concerned with the mode-of-antimicrobial action exerted by metallic copper surfaces.
