This is how cold plasma works on bacteria
Cold atmospheric plasma (CAP) is a partially ionised gas. It creates a reactive mix of electrons, ions, excited atoms and molecules, reactive chemical species (such as O3, NO, NO2, etc.), UV radiation and heat. CAP penetrates the bacterial cell wall as well as the membrane and destroys the intracellular structures, including the DNA, in order to inactivate these microorganisms. In contrast, human eukaryotic cells are significantly better protected, among other things, by the DNA lying in a cell nucleus and, according to previous knowledge, are therefore not damaged by treatment with plasma care®. The patient is neither exposed to radiation nor does electricity flow through the skin. You can find more about plasma technology under “Technology”.
