Initial Study Results from Ongoing EOScu Clinical Trial at the

Olin E. Teague Veterans’ Medical Center


Mean bioburden on copper surface was 81% lower at hour 30 than non-copper

Copper-impregnated tray tables had lower microbial burden than standard material

Bioburden difference between surfaces was statistically significant beyond 24 hours

“We are… going to need new treatments, new aides, new processes to reduce the opportunity for infection, and this, to me, is the beginning of a new wave of products to solve those problems.”
