The Role of Free Radicals in Hemolytic Toxicity Induced by Atmospheric-Pressure Plasma Jet

الملخص EN

Atmospheric-pressure plasma (APP) has received attention due to its generation of various kinds of reactive oxygen/nitrogen species (ROS/RNS).

The controllability, as well as the complexity, is one of the strong points of APP in various applications.

For biological applications of this novel method, the cytotoxicity should be estimated at various levels.

Herein, we suggest red blood cell (RBC) as a good cell model that is simpler than nucleated cells but much more complex than other lipid model systems.

Air and N2 gases were compared to verify the main ROS/RNS in cytotoxicity, and microscopic and spectroscopic analyses were performed to estimate the damages induced on RBCs.

The results shown here will provide basic information on APP-induced cytotoxicity at cellular and molecular levels.
