| Research Abstract |
The antibacterial characteristic1s of 21 kinds of bulk metals and 23 kinds of metal ions were clarified to obtain the basic data for the creation of antibacterial metallic materials. Moreover, the biofilm formation behavior formed on the metal surfaces was observed. As a result, antibacterial properties of the bulk metals such as silver, copper and cobalt, etc. are high, and it has been understood that tin, tantalum, and platinum doesn't show antibacterial properties. The similar tendency was shown in the antibacterial examination with the metal ions. It was shown that the formation of the biofilm was restricted on the metal surfaces where antibacterial property was high.
