(a) Image of the hand-held portable low-temperature plasma jet. (b) Schematic of helium plasma jet for the preparation of PAM. (c) Typical voltage and current waveforms of the helium plasma jet at a discharge power of 1.05 W and voltage of 9 kV. (d) OES measurement of plasma jet discharging with He gas and O₂ gas with a wavelength ranging from 200 to 900 nm. (e) pH value of DI water, PBS, and different exposure times of plasma-activated DMEM medium. (f) The relative level of H₂O₂ and NO_x in different exposure times of PAM. (g) Degradation of H₂O₂ under the storage at −20 and −80°C. (h) Degradation of NO_x under storage at −20 and −80°C. (i) Degradation of H₂O₂ and NO_x under storage at 4°C.
