Ionized plasmas as cheap sterilizers for developing world

Ionized plasmas as cheap sterilizers for developing world: Devices that create ionized plasmas could be life-savers in the developing world or on the battlefield, providing an inexpensive way to sterilize water and medical instruments. Researchers have created low-temperature plasma devices that sterilize water and keep it antimicrobial for at least a week. A new report finds that the hydrogen peroxide and nitrites produced by the plasma discharge are not the source of long-term antimicrobial activity.
