Abstract
A method for treating cancer stem cells with cold atmospheric plasma using a cold atmospheric plasma system The method comprises the steps of placing an exit port of a cold plasma delivery device 5 cm or less from target cancer stem cells, flowing the inert gas from the source through the housing at a flow rate of 5-10 ml/minute, applying electrosurgical energy of 2-5 kV at a frequency of 20-35 kHz to at least one of the central electrode and the ring electrode to produce a cold plasma jet from the exit port, directing the cold plasma jet onto the target cancer stem cells, and applying the cold plasma jet onto the target cancer stem cells for at least 2 minutes. In a preferred embodiment the inert gas is helium.
