Plasma Medicine

Medicine   Arrow up Back to Applied Research

In plasma medicine

the aim is to transfer the knowledge gained through in vitro (and animal) studies into medical practice.
With cold atmospheric plasmas we have the advantage that the toxic products, the UV radiation, the heat generated, electric fields and currents can all be de­termined and regulated quite accurately – and that health regulations already exist. The current studies therefore concentrate on known properties and the appropriate plasma design.

The current task – development of an efficient new antibacterial agent and the associated treatment, which at the same time is harmless to human cells and tissue – is the major immediate challenge.
Consequently, medical applications build on physics, chemistry, engineering and biology in a major way. Many studies are required.

Medical compatibility: ex-vivo skin tests

(probably related to drying).

AFM imaging of bacteria (E. coli)   (from Pompl et al., NJP, 2009)

These measurements indicate that plasma treatment is very effective for killing bacteria, but in the right 'dose' not harmful to mammalian cells.
