Low temperature plasma applications in medicine

Plasma Medicine: A Field of Applied Redox Biology

“…They differ in their plasma generation mechanism, source geometry, working gases, and, consequently, vary in their application characteristics (9,12,(24)(25)(26)(27)(28). During recent years, mainly two fundamental concepts of CAP devices have been tested and are partially applied for medical purposes: i) dielectric barrier discharges (DBD) and ii) plasma jets (9,(29)(30)(31)(32).…”

“…In Figure 1, three technical principles of plasma sources intended for biomedical applications are depicted (11,30).…”

Plasma Farming: Non-Thermal Dielectric Barrier Discharge Plasma Technology for Improving the Growth of Soybean Sprouts and Chickens

“…A number of sources of non-thermal plasma (less than 40 • C) at atmospheric pressure are being optimized and stabilized to ensure their effective and safe biological applications. In recent years, mainly three basic types of non-thermal atmospheric plasma devices, including plasma jet, surface and volume dielectric barrier discharges (DBDs), have been partially applied in cells or tissues [7][8][9][10]. In a plasma jet, the electrode (pin, ring, or plate type) is located in a capillary or tube inside a pen-like device.…”

“…In a volume DBD, the plasma is generated in the gap between an isolated high voltage electrode and target. These three types of non-thermal atmospheric plasma, which are generated inside small discharge gaps, consist of transient micro discharges or filaments with non-uniform and constricted property [10]. In recent years, non-thermal plasma-induced changes in the liquid environment of cells and reactive species generated in or transferred into liquid phases by plasma treatment are identified as the two main basic mechanisms of biological plasma action [10].…”

The detailed analysis of gas and liquid phase chemistries, the generation of energetic photons, and the parameters of the electric field are required for the mode of plasma action and the development of plasma sources for specific applications.…”
