Surface dielectric barrier discharge plasma–treated pork cut parts: bactericidal efficacy and physiochemical characteristics

DBD plasma as a practical approach to sterilization of dental instruments

“…The reaction R(5) also produced oxygen atomic lines, which appeared at a wavelength of 572 nm. In addition, at 693 nm and 871 nm, a sharp line can be seen, indicating the formation of oxygen lines by reaction R (6). Additionally, given that the relative humidity in the working environment is about 60%, the OH A X ( ) å - + lines at 309 nm.…”

“…NO, a molecule that functions as an intracellular messenger and regulator in several biological processes exerts its influence on cell proliferation, phagocytosis stimulation, collagen formation regulation, immunological deficit control, and angiogenesis. Its oxidative potential is measured at 0.90 eV [6,42].…”

“…In humid air, the DBD reactors generate cold plasma which is considered a significant source of reactive oxygen and nitrogen species (RONS) that are highly active. These species, characterized by their high oxidation potentials, include hydrogen peroxide (H 2 O 2 ), hydroxyl radical (OH), ozone (O 3 ), atomic oxygen (O), hydrogen superoxide (HO 2 ), nitrogen dioxide (NO 2 ), and nitric oxide (NO) [6,13]. Multiple studies have presented empirical data supporting the notion that the impact of cold plasma on living organisms, including both prokaryotic and eukaryotic entities, is regulated by the participation of reactive oxygen and nitrogen species (RONS) [14][15][16].…”

“…Generally, cold plasma devices into two main categories: direct discharge devices, such as dielectric barrier discharge (DBD), and indirect discharge devices, such as air pressure plasma jets (APPJ) [5]. The DBD plasma reactor has the advantageous characteristic of having the capacity to effectively treat a substantial surface area (several cm 2 ) and being easy to use in different environments [6]. Currently, dielectric barrier discharge (DBD) plasma is gaining attention because it removes contaminants efficiently and simultaneously produces chemicals that are useful in the degradation of contaminants [7].…”

“…Multiple studies have presented empirical data supporting the notion that the impact of cold plasma on living organisms, including both prokaryotic and eukaryotic entities, is regulated by the participation of reactive oxygen and nitrogen species (RONS) [14][15][16]. The active species ROS and RNS have a significant impact on the process of decontamination by exerting inhibitory effects on various pathogens, such as fungi, dangerous bacteria, and viruses [6]. Over the last several years, the researchers have shown a keen interest in doing investigations pertaining to various prospective clinical and research applications within the field of dental science.…”
