Researchers at the Institute of Food Research have tested a new technique to ensure fresh produce is free of bacterial contamination. Plasmas are a mix of highly energetic particles created when gases are excited by an energy source. They can be used to destroy bacteria but as new research shows, some can hide from its effects in the microscopic surface structures of different foods. Eating fresh fruit and vegetables is promoted as part of a healthy lifestyle, and consumers are...

Because they are portable and easy to operate at ambient temperatures, cold atmospheric pressure plasma jets (APPJs) should find innovative applications in biomedicine, materials science and fabrication industries. Research reported in the Journal of Applied Physics investigates an APPJ that extends from the ground electrode of a circuit. The researchers studied the mechanism of the jet, which differs from conventional APPJ applications that form at the active electrode. "The ground electrode...

Though it looks like a tiny purple blowtorch, a pencil-sized plume of plasma on the tip of a small probe remains at room temperature as it swiftly dismantles tough bacterial colonies deep inside a human tooth. But it's not another futuristic product of George Lucas' imagination. It's the exciting work of USC School of Dentistry and Viterbi School of Engineering researchers looking for new ways to safely fight tenacious biofilm infections in patients "“ and it could revolutionize many...
