Plasma Germ Blaster Gun Invented for Cleaning Skin
5th April 2012
The plasma gun or “flashlight” requires just a 5V battery to produce enough cold plasma to kill even heat-resistant and antibiotic-resistant bacteria such as Enterococcus faecalis (a nasty gastrointestinal bug). Because the plasma’s heat ranges from 20 to 23°C (68 to 73°F), it doesn’t damage the skin. The bacteria-busting raygun – the work of scientists from China and Australia – costs just $100 to manufacture.
