Combining diagnostics for characterizing antibacterial effect of a cold atmospheric plasma source

In the characterisation of an atmospheric pressure plasma jet acting on a biological substrate, a synchronised multidisciplinary approach is needed; multiple diagnostics should be combined. Moreover, given the complexity of the system, it is of fundamental importance to keep constant all the external parameters which can affect the interaction. In this work the plasma, the treated liquid substrate and the biological effects are analysed using a fixed setup, obtaining a set of fully comparable data. The results shows clear trends in the reactive species and in the biological effects, which can be correlated to help the understanding of the involved reactions.
