Reactive oxygen species plasma treatment

WebReactive species, mainly reactive oxygen species (ROS), are products generated by metabolic reactions of cells. In normal cells, low-level concentrations of these compounds are required for signal transduction. However, under pathological conditions such as cancer, cardiovascular diseases, and AMD, the ROS concentration is high.
