“…1 We are interested in applying this probe to determine superoxide in advanced oxidation processes induced by air non thermal plasma. [12][13][14][15][16][17] In repeating some of the experiments used by Lu et al 1 to characterize the probe's behavior, we realized that the procedure they applied to perform experiments with KO2 as a surrogate for superoxide is not appropriate and led them to misinterpret their results. The present comment addresses this issue and provides and discusses experimental evidence of interest for users of this and all related probes for superoxide.…”

Recently, a new water-soluble, fluorescein-based probe for the detection of superoxide radical anion in aqueous media was developed by Lu et al. (ACS Sens. 2018, 3, 59-64). The probe was proven to be selective for superoxide and was used successfully also in cells and zebrafish embryos. To characterize the response of the probe to superoxide, Lu et al. used KO2 dissolved in deionized water as surrogate. In testing this probe in different applications we repeated some of these experiments and came to realize that the fluorescence signal observed by the Authors in their experiments with KO2 was incorrectly attributed to reaction of the probe with superoxide and is due instead to its reactions with HO − and HO2 − . We show that indeed under the conditions used in these assays KO2 undergoes very fast reaction with water to form HO − and HO2 − . On the other hand, by using a proper surrogate, namely KO2 dissolved in DMSO, and spin trapping experiments, we confirmed the ability of the probe to detect superoxide.

“…Giardina, Tampieri, Biondo, Marotta, and Paradisi (2019) tested the degradation of herbicides, such as mesotrione and metolachlor using air nonthermal plasma in a dielectric barrier discharge (DBD) reactor. The results showed that complete mineralization was achieved and that in the presence of air nonthermal plasma mesotrione was considerably more reactive than metolachlor.…”

“…For this reason and due to its flexibility and low costs, it can be utilized for different applications. [ 14,15 ] In the last few years, the dielectric barrier discharge (DBD) plasma discharges have been utilized for the decontamination in aqueous solutions, [ 16,17 ] for bacteria inactivation and sterilization, [ 17‐20 ] and other chemical reactions.

Charge particles can increase the biocidal efficacy of nonthermal plasmas in indirect treatments. The aim of this study is to increase the amount of free charges produced and delivered by a surface dielectric barrier discharge fluid‐dynamics actuator. Different linear actuators and supplying conditions have been considered. Actuators were utilized to produce an ionic wind impinging an insulating target surface. Charged particles' distribution over the target was measured with and without a metallic mesh between the actuator and target itself. Linear actuators have proven to be more effective in charge delivery with respect to an annular one previously studied by our research team. A two‐dimensional electrostatic finite‐element analysis has been carried out to get a better insight into this physical behavior.
