The plasma jet is shielded from the atmosphere by different mixtures of oxygen and nitrogen gas. Different liquids with increasing complexity in ingredient composition (namely, sodium chloride solution, Dulbecco's phosphate-buffered saline solution, and Roswell Park Memorial Institute cell culture medium) were plasma treated and the formation of reactive species was studied. By varying the shielding gas composition, the type and quantity of generated reactive species, reactive nitrogen species, or reactive oxygen species can be tailored. This study shows that the ingredients of the plasma-treated liquid strongly influence the reactive species formation.
