Today's story was passed along to me by one of your classmates. In the article (abstract found here), a group of scientists was studying the feasibility of using non-thermal plasma to kill bacteria in a wound. Currently, almost all wound-associated antimicrobials are chemical agents. These may have limited ability to kill bacteria that is naturally resistant, or that lives in a biofilm (as most bacteria do). In their research, they discovered that treatment with non-thermal plasma reduced the number of colony forming units in both a rat model and biofilm. While the study is very preliminary, it may eventually lead to a novel form of treatment for infected wounds.
