Clinical Studies and Proof

Aereus Shield has been evaluated in lab and real-time hospital conditions.

“Copper is the only surface that we know reduces bacterial counts in patient environments. Our study at Toronto General Hospital showed that copper alloy coatings have persistent antimicrobial activity. These coatings could be highly valuable in healthcare settings.” – Dr. McGeer, Infectious Disease Consultant and Microbiologist, Mount Sinai Hospital 


VirusBacteria in lab settings suffered from membrane perforation within minutes. Research showed that the cell was quickly corrupted, starving the bacteria of vital nutrients before its DNA can replicate. Most of the microbes exposed to Aereus Shield were cleared within twenty minutes, however within two hours 99.9% of the bacteria were eliminated completely.

A bacteria lethality study at the University of Toronto’s Cell and Systems Biology department proved that Aereus Shield was roughly 20% more effective than EPA-certified solid copper and 60% more effective at killing bacteria than steel.


Wiley JournalA white paper published in the Journal of Applied Microbiology verifies Aereus Shield’s efficacy and highlights the coating’s unique surface roughness as being an important quality. Read the Abstract or click here for the white paper.

Caught in the coating’s macroscale dimples, bacteria is exposed to a greater copper surface area.


TGH-chairsIn healthcare settings, Aereus Shield was shown to persistently reduce bacterial load by a median of 66%. These findings were presented at ICAAC in September, 2013. Aereus Shield coated chair arms in a busy out-patient waiting room. Both sets of chairs were disinfected with cleaning products between swabbing days. Even after cleaning, Aereus Shield chairs still had 66% less bacteria than the sterilized plastic chairs sitting beside them.
