Plasma Applications and Diagnostics

Cold atmospheric plasma — an ionized gas generated near room temperature — produces a controlled mixture of reactive oxygen and nitrogen species that can selectively damage cancer cells, inactivate pathogens, and accelerate wound healing without the thermal harm associated with conventional plasma. Researchers are working to understand precisely how these reactive species interact with biological tissues at the molecular level, since the mechanisms that make plasma lethal to bacteria or tumors while sparing healthy cells remain incompletely characterized. Active directions include optimizing plasma sources for clinical settings, establishing safe and reproducible dosimetry, and determining whether plasma-generated species can be delivered in stable liquid form for applications where direct gas exposure is impractical.
