design and construction of triplet atmospheric cold plasma jet for sterilization
نویسندگان
چکیده
in this paper, construction of triplet atmospheric plasma jet using argon, air, oxygen and nitrogen gases is reported. bactericidal effect of the plasma jet is also investigated. to that end, longitudinal geometric configuration for the electrodes was chosen because it would increase the jet length. electrical characteristics, jet length dependencies on the applied voltage and gas flow rate were decided, experimentally. relative concentrations of chemical reactive species such as ozone, atomic oxygen, nox compounds and hydroxyl were measured using optical emission spectroscopy. it was seen that atomic oxygen and ozone concentrations with triplet plasma jet are more than the concentration of single plasma jet. triplet plasma jet was also used for sterilization of solid and liquid surfaces to disinfect gram-negative and gram-positive escherichia coli and streptococcus pyogenes bacteria. the results verified the effectiveness of the triplet plasma jet for killing bacteria.

In this research, a non-thermal atmospheric pressure plasma jet device was constructed for skin wound treatment. For this reason, five mice were treated for five consecutive days for 30 s, in a daily manner. Natural wound healing time was monitored and compared with the treated one in 12 consecutive days. The measurement of voltage, current and power waveforms of the plasma source, the optical ...
