A recent study proves that antimicrobial copper effectively kills MRSA within two hours while it readily survives on stainless steel. Antimicrobial copper is part of the solution in the fight against healthcare-acquired infections. The MRSA culture was stained with a green fluorescent dye to make it visible under a microscope, and then placed on antimicrobial copper and stainless steel. As the bacteria died off, the fluorescence diminished. The rate of diminishing fluorescence was a measure of the antimicrobial power of the surface on which it had been placed. The stainless steel surface showed little fade, indicating the surface had no antimicrobial activity.
