The invention (patent pending) directs cold plasma from different orientations to keep surfaces disinfected without hand sanitizer, sprays, ultraviolet light or other chemical-based solutions. “This is a continuous, in-situ answer to disinfecting surfaces that people touch frequently,” said Charles Gentile, one of the PPPL inventors. He developed the technology with Kenneth Silber, a 38-year professional in PPPL Information Technology’s department. The technology could be used on such surfaces as subway poles and turnstiles, elevator button keypads, touch screens, vending machines, ATMs, slot machines, retail payment ATMs, grocery conveyor belts, elevator handrails, building intercoms, entry door handles and push bars, and shared microphones, to name a few examples.
