The plasma jet transfer maintained an almost uniform temperature along the 90 cm transfer path and at the jet tip. Comparative antibacterial assays against dominant pathogens suggested that argon gas exhibits significantly greater bactericidal activity than helium, which aligns with its higher generation of reactive oxygen and nitrogen species, as evidenced by its emission spectra.</span></span></span></span></span><br> <b><span style="font-size:10.5pt"><span style="line-height:107%">Conclusion: </span></span></b><span style="font-size:10.5pt"><span style="line-height:107%">Our findings show that the developed plasma jet transfer system, with its low operating temperature and minimal power consumption, is well-suited for biomedical use. Its ability to deliver cold plasma through flexible tubing without compromising performance opens opportunities for safe applications in wound care, sterilization, and minimally invasive therapies without the risk of thermal damage to surrounding tissues.</span></span></span></div> <br> &nbsp; <table align="center" border="1" cellpadding="0" cellspacing="0"> <tbody> <tr> <td></td> <td><img alt="" height="84" src="./files/site1/images/Picture1.jpg" width="507" ></td> <td></td> </tr> </tbody> </table> Cold plasma, Medical application, Plasma Jet transfer, Reactive oxygen-nitrogen species 27 27 http://ibj.pasteur.ac.ir/browse.php?a_code=A-10-1-889&slc_lang=other&sid=1 Sina Lotfian No Farshad Sohbatzadeh No Fatemeh Jamshidi Alashti Yes
