Thank you dear Sumit Bhowmick for your interesting question, actually it is about Cold Atmospheric plasma

Cold Atmospheric Plasma is an ionized gas that has recently been extensively studied by researchers as a possible therapy in dentistry and oncology. Several different gases can be used to produce  Cold  Atmospheric Plasma such as Helium, Argon, Nitrogen, Heliox, and air.

Projects on plasma medecine generally target the use of cold plasmas (those generated in different gas or gas mixtures by corona discharges, or dielectric barrier discharges or the usual plasma jets or microwave plasmas etc.) for the inactivation of cancer cells, or for wound healing or surface decontamination or sterilization ... This in act concerns the interactions of the plasma species (ROS or RNS or charged particles) and even the electric field with various cells to obtain a specific effect in the field of cancer or healing or decontamination and also in agriculature to for instance stimulate germination or plant growth. You can find in the periodic international conference http://icpm8.or.kr/ the numerous topics involved in this field of 'Plasma medicine'. I hope that my answer is what you expect.
