Low temperature plasma biomedicine: A tutorial reviewa)

摘要: Gas discharge plasmas formed at atmospheric pressure and near room temperature have recently been shown to be potentially useful for surface wound sterilization, antisepsis, bleeding cessation, healing, cancer treatment, among other biomedical applications. This tutorial review summarizes the field, stressing likely role of reactive oxygen nitrogen species created in these as biologically therapeutically active agents. Reactive species, including radicals non-radical compounds, are generated naturally within body now understood essential normal biological functions. These known agents existing therapies infection control, treatment. But they also observed elevated levels persons with many diseases associated aging. The physical chemical complexity plasma medical devices their biochemical effects makes development safe, effective procedures a challenge, but encouragingly rapid progress has reported around world last several years.
