Plasma is highly efficient in the inactivation of microorganisms and tried to be applied treatment wounds. The gas activated by plasma, named plasma-activated gas, can also effectively inactivate get rid limitations direct plasma treatment. However, details interaction on tissue are still unclear. In this study, agarose gel models presence simulate infected tissues were used study effects mechanisms gas. depths related types species microorganisms. Mixed-gas exhibited strongest effects, bacteria deeper than those fungi. long-lived penetrated more 5.2 mm while short-lived only less 2.3 mm, demonstrating distinct roles reactive process. Moreover, pig muscle was covered assess penetration focused could penetrate 1–1.5 muscle. This explored real which supplied theoretical basis for further application biomedical fields.
