However, there are some remarks on the justification of objectives of the study and presentation of the results.
The other potentially inactivating components of the plasma are not specified in the manuscript. For the argon-oxygen gas mixture it is stated that ‘high amounts of reactive oxygen species are formed in the plasma’ again without any qualitative and quantitative description. Estimations of the average free length of path for the inactivating plasma components might have been helpful for experiment planning.
