The Physical Effects of Plasma Medicine on Cells: Radio Frequency Stimulated Intercellular and Intracellular Mechanical Waves

L. Lin;V. Soni;X. Yao;D. Yan;M. Keidar

2022 IEEE International Conference on Plasma Science (ICOPS)
Year: 2022 | Conference Paper |
In the last decade of research works upon plasma medicine using cold atmospheric plasmas (CAP), reactive oxygen and nitrogen species (RONS) are believed to be the major role of these applications. This thus raises the indirect treatments that use the plasma-treated solutions or drugs rather than treat the targeting cells or tissues directly with CAP. However, the difference between direct and indi...Show More
