“…However, the most used wastewater bio-treatment processes including activated sludge and biofilter can't efficiently remove SMX due to its strong hydrophilicity, high stability and antibacterial nature [2,3]. In recent years, discharge plasma technologies have obtained extensive attentions on treating various pollutants [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Electric discharge in water or over water surface produces many kinds of physiochemical effects such as UV irradiation, shockwave, local high temperature, radical and excited state species [19][20][21][22].…”

“…A rapidly evolving technology showing a strong potential for biomedical applications is cold plasma operating at atmospheric pressure (Cold Atmospheric Plasma, CAP) ( 6 ). CAP is generated from electrical energy allowing the creation of high energy electrons and reactive oxygen and nitrogen species (ROS/RNS) such as 1 O 2 , OH radicals, NO x , atomic O, O 3 and H 2 O 2 which play critical role in transferring the reactivity from the gas discharge plasma zone to solutions/media ( 7 ), subsequently inducing specific biochemical responses. CAP has been used in several branches of modern medicine, such as in wound healing and sterilization ( 8 ).…”

Breast cancer exists in multiple subtypes some of which still lack a targeted and effective therapy. Cold atmospheric plasma (CAP) has been proposed as an emerging anti-cancer treatment modality. In this study, we investigated the effects of direct and indirect CAP treatment driven by the advantageous nanosecond pulsed discharge on breast cancer cells of different malignant phenotypes and estrogen receptor (ER) status, a major factor in the prognosis and therapeutic management of breast cancer. The main CAP reactive species in liquid (i.e. H2O2, NO2−/NO3−) and gas phase were determined as a function of plasma operational parameters (i.e. treatment time, pulse voltage and frequency), while pre-treatment with the ROS scavenger NAC revealed the impact of ROS in the treatment. CAP treatment induced intense phenotypic changes and apoptosis in both ER+ and ER- cells, which is associated with the mitochondrial pathway as evidenced by the increased Bax/Bcl-2 ratio and cleavage of PARP-1. Interestingly, CAP significantly reduced CD44 protein expression (a major cancer stem cell marker and matrix receptor), while differentially affected the expression of proteases and inflammatory mediators. Collectively, the findings of the present study suggest that CAP suppresses breast cancer cell growth and regulates several effectors of the tumor microenvironment and thus it could represent an efficient therapeutic approach for distinct breast cancer subtypes.

“…Various layers of low-melting materials are coated onto temperature-sensitive substrates [9][10][11][12]. The antibacterial properties of non-equilibrium plasmas are used and intensively explored in food and medical industries [13][14][15][16]. In the environmental sector, such plasmas are used to neutralize industrial waste gases by the selective removal of chemical compounds [8,17,18].…”

“…Moreover, possible applications to increase efficiency in the production of synthetic fuels are being explored [19,20]. As a result of the ever-widening range of applications, especially in the environmental and health fields [13,[20][21][22][23], the need for the comprehensive characterization of non-thermal plasmas seems to become more and more important.…”

Spectroscopic Characterization of a Pulsed Low-Current High-Voltage Discharge Operated at Atmospheric Pressure

et al. 2022

The advantages of pulsed low-current high-voltage discharges operated at atmospheric pressure and the ease with which such discharges can be implemented industrially contributed to their popularity. However, the high reactivity of a pulsed plasma implies that thorough diagnostics are needed to fully understand the interactions inside these plasmas. Some of the key parameters determining plasma properties of low-current discharges are the electron number density and the temperature of heavy particles. Both parameters can be determined experimentally with spectroscopic techniques, for example by investigating the broadening of spectral lines due to the Stark effect and by fitting synthetic spectra to molecular transitions. To the authors’ knowledge, experimentally determined electron densities for pulsed low-current discharges operated in a power range between 300 W and 1000 W have not been performed in previous works. Thus, in this work, the electron number density and temperature of heavy particles of one of several commercially available plasma systems are determined by means of emission spectroscopy.
