Description:
Chemically Enhanced Plasma Sterilizer
Princeton Docket # 20-3703
Researchers at Princeton Plasma Physics Laboratory, Princeton University have designed a chemically enhanced plasma sterilizer (CEPS) which uses atmospheric pressure cold plasma enhanced with a chemical reagent and UV light to provide sterilization and disinfection of bio-contaminated surfaces such as skin of human hands (with minimized UV), face masks, gloves, medical bandages, thin non-conductive and weakly conductive materials (e.g. paper, rubber, fabric, leather). Compared to the existing plasma-based sterilization devices, a key novelty of the CEPS is in a unique combination and synergy of bioactive plasma properties which include chemically active radicals, UV, electric field at the plasma-surface interface, surface charging, current, with the treatment of a large surface area. The CEPS are both scalable and useable by an individual consumer.
The U.S. Department of Energy's Princeton Plasma Physics Laboratory is a Collaborative National Center for plasma and fusion science. Its primary mission is to develop the scientific understanding and the key innovations which will lead to an attractive fusion energy source. Associated missions include conducting world-class research along the broad frontier of plasma science and providing the highest quality of scientific education.
