Nitrite (NO2¨C) detection by Griess Reagent. 50 ¦ÌL of the sample was taken and
transferred into a cuvette and combined with 50 ¦ÌL of Griess Reagent and 0.9 mL of Milli-Q
water. The resulting sample was mixed thoroughly. The mixture was incubated at room
temperature in the dark for 0.5 h prior to UV-Vis testing. Solutions of NaNO2 with known
concentrations (in 10 mM H2SO4) were used as calibration standards, with the absorbance at
525 nm used to plot the calibration curves. Upper LOD of UV-Vis used in this study refers to
the absorbance at 525 nm obtained from 200 ¦ÌM NaNO2. A dilution factor was applied to
measure nitrite concentration in plasma-activated water (PAW)
