Abstract :
An atmospheric-pressure nanosecond pulsed plasma jet was directed into a dielectric microtube to form a curving plasma needle and fill the entire volume of the tube. The bactericidal effect of the plasma was demonstrated against Enterococcus faecalis biofilms, which were grown on the inner surfaces of the tubes.
