“…Atmospheric pressure non-thermal plasmas have expressed broad prospects in many fields because of their remarkable chemical activity achieved at a gas temperature near room temperature [1][2][3][4][5]. In some specific areas such as water purification and plasma activated water preparation, the plasmas inevitably come into contact with the liquid [6][7][8][9][10].…”

Transient spark discharge has a broad application prospect due to its excellent performance in generating reactive oxygen species, but there is currently limited research on the transient excited species which are the important precursors for the formation of these species. This paper obtained a transient spark discharge with a needle-water electrode configuration, and then developed an optical detection system based on photomultiplier to measure the temporal evolution of four excited species. It is observed that N2 (C) is produced mainly in the streamer phase while H (n=3), O (3p), and OH (A) are produced mainly in the spark phase, which is resulted from the difference in threshold energy and pathway for generating different species. To investigate the variation mechanism of peak time and peak intensity during the evolution process, the gas temperature T g, electron density n e, and electron excitation temperature T exc were calculated by using the optical emission spectroscopy under different pulse voltage and pulse repetition frequency conditions. The results indicate that the discharge conditions influence the physical parameters of T g, n e, and T exc as well as the output voltage waveform, and then they jointly determine the evolution characteristics of excited species. These insights contribute to understand the characteristics of excited species which affect the formation of reactive species by influencing the chemical chain reaction in the transient spark discharge.

“…In previous studies, the application of ARTP to organisms has been more about lethal damage and the inactivation of organisms. [74][75][76] In recent years, an increasing number of researchers have found that sublethal effects on cells can be achieved by controlling the power and treatment time of ARTP, 11 and beyond a certain range, lethal effects can occur, thus extending the application of biological mutagenesis. 77,78 The different biological effects resulting from the interaction between ARTP and organisms are achieved through a series of complex reactive processes.…”

At present, atmospheric and room‐temperature plasma (ARTP) is regarded as a new and powerful mutagenesis technology with the advantages of environment‐friendliness, operation under mild conditions, and fast mutagenesis speed. Compared with traditional mutagenesis strategies, ARTP is used mainly to change the structure of microbial DNA, enzymes, and proteins through a series of physical, chemical, and electromagnetic effects with the organisms, leading to nucleotide breakage, conversion or inversion, causing various DNA damages, so as to screen out the microbial mutants with better biological characteristics. As a result, in recent years, ARTP mutagenesis and the combination of ARTP with traditional mutagenesis have been widely used in microbiology, showing great potential for application. In this review, the recent progress of ARTP mutagenesis in different application fields and bottlenecks of this technology are systematically summarized, with a view to providing a theoretical basis and technical support for better application. Finally, the outlook of ARTP mutagenesis is presented, and we identify the challenges in the field of microbial mutagenesis by ARTP.

“…Nitrous oxide (N 2 O), which is also known as laughing gas, exerts a mild anesthetic effect that reduces pain; thus, it is typically used in dentistry and minor surgeries [13,14]. Peroxynitrous acid (ONOOH), which is a strong oxidant and nitrating agent, is crucial in the antibacterial defense of organisms and can traverse biological membranes to damage cellular components owing to its significant cytotoxicity, thereby inducing the death of harmful cells [15,16].…”

The dose regulation of reactive nitrogen species is crucial for biomedical applications. In this study, we developed a global chemical kinetics model comprising 92 species and 1018 reactions to investigate the regulatory dynamics of three types of reactive nitrogen species, i.e., NO, N2O, and ONOOH, which vary with the discharge voltage in an air coaxial dielectric barrier discharge. Based on the experimental results, the model can describe the density variations of NO, N2O, and ONOOH. The simulation results indicate that the O, NO3 - , NO2 - , and O3 are essential intermediate species related to NO generation; N, NO2, O-, N2 *, and O(1D) are essential intermediate species related to N2O generation; and O2 -, NO, NO2, OH, O4 -, and O3 are essential intermediate species related to ONOOH generation. The individual and comprehensive effects of the energy density and gas temperature on the density of NO, N2O, and ONOOH and the corresponding intermediate species are quantified under increasing discharge voltages. The simulation results indicate that the energy density is the primary factor affecting the number density of NO, N2O, and ONOOH, whereas the gas temperature exerts a completely different effect on these three species. These insights are valuable for plasma applications in biomedicine, where the selective and controlled production of reactive nitrogen species is the key for achieving the desired plasma performance.
