Plasma activated liquids (PALs) generated by emergi
ng plasma source are re
ceiving a lot of attention
in biomedical applications since the antibiotic activ
ities for bacteria and cancer cells. It is open
reported that the reactive oxygen and nitrogen
species (RONS) in the liquids induced by the
interaction between emerging plasma and ambient air
, and the RONS diffused into liquid. In this
work, we focused on how to enhance the production
rate of RONS and suggested a usage of micro-
sized orifice for gas jet.
