When a tumor is removed, single cells or cell clusters can remain at the wound edges. They could eventually make another surgery necessary. Prof. Hans-Robert Metelmann and Dr. Christian Seebauer outline in our video how physical plasmas could be used here in the future. Dr. Kai Masur from the Leibniz Institute for Plasma Science and Technology e.V. (INP Greifswald) explains how plasmas turn off tumor cells.
