Microscopic organisms, yeasts, and infections are quickly killed on metallic copper surfaces

Contact killing" is the term associated with killing of Bacteria by Copper

This phenomenon was already known in ancient times,

In the recent year this is getting current attention

After an extended period of incubation, no live bacteria were typically recovered from copper surfaces.

Contact killing of bacteria  observed to occur at a rate of at least 7 to 8 logs per hour.

Copper has recently been recognised with the US Environmental Protection Agency as the first solid antibacterial material.

Copper and copper alloys have long been known for their antimicrobial properties.
