The presentation reviews modern achievements in using non-
thermal plasma for different applications in biology and
medicine. Specific features of non-equilibrium atmospheric
pressure discharges attractive for biological and medical
applications are to be discussed. Primary attention will be
focused on such discharges as: dielectric-barrier discharge
(DBD) in homogeneous and streamer modes; RF atmospheric
pressure glow discharges (RF APG); corona and pulsed corona
discharges; gliding arc discharges. Especially novel discharges
in liquids efficient for bio-medical applications are to be
discussed.
Specific non-thermal plasma applications in biology and
medicine will be subdivided into three major groups: different
kind of sterilization processes; surface treatment and tissue
engineering processes; direct cold plasma applications in
medicine.
Sterilization processes are to be considered separately for
treatment of different surfaces, treatment of air, and
treatment of water (and other liquids). Specifics related to
bacteria, viruses, spores will be addressed. Disinfection is to
be compared with low-temperature burning out and complete
disintegration. Major sterilization mechanism related to atoms
and radicals (OH et al.), ozone, UV, charged particles, excited
molecules (singlet oxygen et al.), micro-shocks are to be
discussed. Kinetic modeling of plasma sterilization processes
will be demonstrated.
Surface treatment and tissue engineering applications will be
discussed using as an example DBD bio-printer experiments.
Direct plasma-medical applications are to be considered using
as examples: non-thermal plasma cauterization and blood
coagulation; non-thermal plasma treatment of wounds; and non-
thermal plasma treatment of skin deceases. Mechanisms of the
non-thermal plasma effects in medicine will be discussed;
detailed kinetic modeling of the plasma-medical processes is to
be compared with experiments.
