Battery-Powered Plasma Flashlight Makes Short Work of Bacteria

cylonlover writes "An international team of scientists has created a handheld, battery powered device that has been shown to effectively rid skin of bacteria in an instant by blasting it with plasma. The plasma flashlight, which shouldn't be confused with a plasma torch that will damage much more than bacteria if used on the skin, could provide a convenient way for paramedics and military personnel to deal with harmful bacteria in the field. The self-contained device is powered by a 12 V battery and doesn't require any external gas feed or handling system. The plume of plasma it generates is between 20-23C (68-73.4F), so it won't damage the skin. It is also fitted with resistors to stop it heating up and becoming too hot to touch. Its creators say it can also be easily manufactured at a cost of less than US$100 per unit."

You take for granted the skin that acts as a physical barrier between the microbes that live on your body. For injuries such as severe burns and auto accidents involving road rash victims are not so lucky. This device sounds like an amazingly suitable solution that provides minimal interferance/physical contact. Although in this context, the irony of using a plasma to disinfect such wounds is not lost.
