“…A UV-irradiated plasma system was used to enhance NO production without chemical interference while maintaining a gas temperature that severely affects fruit quality. UV irradiation rapidly decomposes O 3 , which acts as a scavenger of NO, and decomposes HONO species into NO and hydroxyl radicals (OH • ) [27][28][29]. Photolysis not only increased the NO generation time by more than 100 s but also increased the NO content by more than 200 ppm after 10 min of operation.…”

Nitric oxide (NO) generation-enhanced atmospheric-pressure plasma technology has been investigated as a nonthermal intervention technology for prolonging the ripening period of tomatoes. UV-irradiated dielectric barrier discharge plasma reaches the NO-enhanced mode earlier, and NO is rapidly involved in the inhibition of tomato respiration. With as little as 26 W of power in total, the NO-processing of tomatoes using plasma technology helps control the postripening of tomatoes. The NO-enrichment mechanism was analyzed through numerical calculations, which revealed that the photolysis of ozone (O3) and nitrous acid (HONO) occurred during UV irradiation. The measured amount of CO2 emitted from plasma-treated tomatoes was ~ 300 ppm lower than that emitted from nontreated tomatoes, indicating that metabolism and respiration were inhibited. In addition, the NO-enhanced plasma treatment of tomatoes is considered to be more effective because the so-treated tomatoes emitted 100 ppm less CO2 than the plasma-treated tomatoes. The delay of respiration through plasma treatment can help prevent color changes or decreases in the firmness of tomatoes.

Cold atmospheric plasma (CAP) is a novel technology with boundless significance that can be used in the medical sector that offers noninvasive in-vivo applications without damaging the living tissues. CAPs can be obtained by curtailing the concentration of high-energetic electrons per phase and by freezing molecules/atoms (devoid of charge) in plasma utilizing gas circulation and atmospheric air, which includes a variety of charged and neutral reactive entities, UV rays, electric currents, and fields, etc. that have an influence on cellular material in a multitude of diverse manners. Reactive oxygen species (ROS) and reactive nitrogen species (RNS), produced by the plasma, essentially cause biological and therapeutically advantageous plasma effects. CAP plasma has several important biological functions, including the deactivation of pathogens, induction of tissue restoration and cell propagation, the annihilation of cells by triggering apoptosis, etc. Several fundamental concepts are defined, even if the precise process of the effect of plasma on biomolecules is still not properly identified. Depending on the biological synthesis of RNS and ROS in reactions to plasma emissions, the present review described several aspects of plasma therapy in neuroscience, particularly in anti-glioblastoma, neuro-differentiation, and neuroprotection and also the various applications of CAP in medical fields where it is used in the therapy of SARS-CoV-2, cancer therapy, and chronic and acute wounds. Furthermore, the proliferation in stem cells, dental medicines, dermatology, and a brief insight into CAP devices and their risk factors was highlighted.

The atmospheric pressure plasma in water has numerous applications, including utilizing reactive species in the dye degradation process for polluted water remediation. In the current study, an air plasma jet generated atmospheric pressure plasma, transporting reactive oxygen and nitrogen species (RONS) onto the solution surface, such as OH and NO2 radicals, which immediately developed in an aqueous solution. The identification and concentration of radicals are determined using photoluminescence spectroscopy (PL) and irradiation over the surface of an aqueous solution. Based on the reaction between hydroxyl ions and terephthalic acid, fluorimetric methods for hydroxyl ions determination are developed. In addition, 2,3-diamino naphthalene was selected for the nitrite reaction. The jet nozzle-to-solution-surface distance, treatment time, and carrier air flow rate substantially impacted determining the radical’s concentration in aqueous solution.
