Validation of colorimetric assays for hydrogen peroxide, nitrate and nitrite ions in complex plasma?treated water solutions

Liquids treated with cold plasma emerged as ‘redox drugs’ in biomedicine, sources of reactive oxygen and nitrogen species targeting cellular functions, including wound healing cancer progression. The use cell culture media starting liquid, however, challenges the identification plasma-generated chemistry, limited by presence many organic compounds. Available detection methods need, therefore, to be confirmed these liquids avoid inaccurate results. In this research, robustness, linearity, accuracy specificity three colorimetric assays are investigated detect H2O2, NO2? NO3?, predominant plasma-induced products. results clearly highlight some factors affecting like high concentrations chlorides found interfering NO3? medium.
