Dipla is a compact non-thermal plasma generator for medical applications.
Cold plasma is a special physical plasma, which is not in local thermodynamical equilibrium. Heavier particles like Ions and Atoms stay at room temperature, while only the much lighter electrons have a high temperature. So it can be used on any living tissue because any thermal effects are neglectable.
Cold plasma consists of several active species, who all contribute to the beneficial effects. There is electromagnetic radiation (IR, visible light, UV), static electric fields, Ions and electrons, excited molecules and atoms and reactive oxygen and nitrogen oxide species.
