Antimicrobial copper-alloy touch surfaces
Antimicrobial copper-alloy touch surfaces can prevent frequently touched surfaces from serving as reservoirs for the spread of pathogenic microbes. This is especially true in healthcare facilities, where harmful viruses, bacteria, and fungi colonize and persist on doorknobs, push plates, handrails, tray tables, tap (faucet) handles, IV poles, HVAC systems, and other equipment. These microbes can sometimes survive on surfaces for more than 30 days.[citation needed]
Coppertouch Australia commissioned the Doherty Institute at the Melbourne University Australia to test its Antimicrobial Copper adhesive film. Lab tests proved a 96% kill rate of Influenza A virus with the film as compared to non treated surfaces.[citation needed]
The surfaces of copper and its alloys, such as brass and bronze, are antimicrobial. They have an inherent ability to kill a wide range of harmful microbes relatively rapidly – often within two hours or less – and with a high degree of efficiency. These antimicrobial properties have been demonstrated by an extensive body of research. The research also suggests that if touch surfaces are made with copper alloys, the reduced transmission of disease-causing organisms can reduce patient infections in hospital intensive care units (ICU) by as much as 58%. Several companies have developed methods for utilizing the antimicrobial functionality of copper on existing high-touch surfaces. LuminOre and Aereus Technologies both utilize cold-spray antimicrobial copper coating technology to apply antimicrobial coatings to surfaces.
As of 2019 a number of studies have found that copper surfaces may help prevent infection in the healthcare environment.
Microorganisms are known to survive on inanimate surfaces for extended periods of time. Hand and surface disinfection practices are a primary measure against the spread of infection. Since approximately 80% of infectious diseases are known to be transmitted by touch, and pathogens found in healthcare facilities can survive on inanimate surfaces for days or months, the microbial burden of frequently touched surfaces is believed to play a significant role in infection causality.
On February 29, 2008, the United States Environmental Protection Agency (EPA) approved the registrations of five different groups of copper alloys as "antimicrobial materials" with public health benefits. The EPA registrations now cover 479 different compositions of copper alloys within six groups (an up-to-date list of all approved alloys is available). All of the alloys have minimum nominal copper concentrations of 60%. The results of the EPA-supervised antimicrobial studies demonstrating copper's strong antimicrobial efficacies across a wide range of alloys have been published.
The bacteria destroyed by copper alloys in the EPA-supervised antimicrobial efficiency tests include:
The registrations are based on studies supervised by EPA which found that copper alloys kill more than 99.9% of disease-causing bacteria within just two hours when cleaned regularly (i.e., the metals are free of dirt or grime that may impede the bacteria's contact with the copper surface).
