Cold plasmas move on Researchers have developed a new hand-held device that can produce room-temperature plasmas for biomedical applications. The source, which was developed by Mounir Laroussi and XinPei Lu at the Old Dominion University in Virginia, could be used to kill bacteria, heal wounds and treat plaque (Appl. Phys. Lett. 87 113902). At atmospheric pressure, most plasmas are so hot (thousands of degrees centigrade) that they would immediately kill any living cells they come into contact with.
