About antibacterial property of Brass
Brass is known that metal are contained Copper ion’s oligodynamic action can kill bacteria.

Copper ions affect the homeostasis of microorganisms and cause cell damage.

After that, the cytoplasm flows out from the damaged site, and the active oxygen generated by copper ions damages the cells and eventually even the DNA. (Note 1)

In a demonstration experiment conducted by the Japan Copper Center, a copper plate was placed on agar containing O-157 bacteria, and it was found that as a result of culturing the bacteria, breeding was stopped around the copper plate. As a result of passing the number of infections by contacting the influenza virus with copper, it was found that 75% of the virus was killed 1 hour later, and decreased to 0.025% 6 hours later.

In addition, it has been proved to be effective against various bacteria such as methicillin-resistant Staphylococcus aureus (MRSA), and it is expected to be used in water supply facilities of hospital facilities in the future. (Note 2)
