Antibacterial treatment of Escherichia coli on agar media in a sterile petri dish (a) hairline plasma on an agar surface (grounded electrode in agar bulk not shown; white arrows indicate moving direction) (b) expanded view of the plasma filament (c) Escherichia coli contaminated agar plate after treatment and overnight incubation. The plasma treated path is marked by the orange box and a detailed view is shown in the inset).

FIG. 6.

Application of plasma filament to a prepared root canal of a human tooth in a grounded bulk of meat. Half of the tooth was ground off to expose the canal and the specimen was covered with a coverslip. (a) Plasma filament applied more to the wall of the root canal and (b) plasma filament adjusted to treat the tip of the root canal. Different levels of brightness are chosen for clarity.
