Scientific Studies

Antimicrobial Copper alloys are the first solid surface materials registered and certified by the EPA to kill 99.9% of bacteria that can cause infections. Their effectiveness is tested and proven; antimicrobial alloys are medical-grade alternatives to traditional materials such as stainless steel in healthcare, education, hospitality, transportation, and public applications. Working by destabilizing bacterial cell walls, viral envelopes, and destroying DNA.........EPA registered copper alloys are the only metal alloys able to make bacteriacidal claims. At US Infection, we work with top manufacturers to upgrade your facility's high risk touch surfaces, HVAC, and other systems to help your community combat transmission of diseases such as Influenza and MRSA.

Rigorous testing proves that antimicrobial copper alloys are more effective at killing bacteria compared to traditional materials such as stainless steel, plastic and wood. 

Examples of Healthcare Associated Infections (HAIs) decreased by antimicrobial copper alloys:  

     •     Staphylococcus aureus

     •     Methicillin-Resistant Staphylococcus aureus (MRSA)

     •     Vancomycin-Resistant Enterococcus faecalis (VRE)

     •     E. coli O157:H7

     •     Pseudomonas aeruginosa

     •     Enterobacter aerogenes

     •     Clostridium Difficile

     •     Influenza

     •     Norovirus

There has been ongoing and recently commenced clinical trials in active Intensive Care Units and healthcare facilities proving the benifits of copper. These studies further support the results of the EPA testing – copper alloys reduce bacteria continuously and consistently. Below are several of these studies:


2012 Study

2013 Study

2015 Study


Survival of bacteria on copper is enabled by patches of dirt, emphasizing the need for routine cleaning of antimicrobial copper surfaces. There have not been any superbugs found to be naturally resistant to copper. There are several reasons to suggest resistance will never be possible:

1. The genetic material of bacteria is completely degraded during contact-killing, preventing the transfer of resistance genes to other organisms.

2. Contact-killing is very rapid and cells are not dividing on copper surfaces, precluding the acquisition of resistance.

3. Copper and copper alloys have been used by humans for thousands of years, yet, there has not been a resistant bacteria strain discovered.
