Summary: Cold atmospheric-pressure plasma (CAP) is a promising virus disinfection technique that can effectively inactivate various viruses in a short period. The simultaneous action of physical and chemical means is the key mechanism of CAP in virus inactivation. Nevertheless, there are still opportunities and challenges faced by plasma virus inactivation technology.

Summary: Cold atmospheric plasmas used in plasma medicine have great potential, but determining plasma dosage is challenging. This study employed the ratio of discharge energy to treated cell number and median lethal dose to define plasma dosage, with LD50 for kidney cells being 34.67 mJ/cell.

Summary: This study investigates the effect of cold atmospheric pressure plasma (CAPP) on seeds and its relation to plasma parameters. The most advantageous treatment for soybean seeds was found to be the use of ambient air plasma. The water contact angle of samples treated directly in plasma was significantly smaller than that of samples treated with gaseous products. Optical emission spectroscopy (OES) and Fourier transform infrared spectroscopy (FTIR) were used to study the plasma parameters.

Summary: This review evaluates the potential of cold atmospheric plasma (CAP) as a method for inactivating foodborne viruses. CAP has been shown to successfully inactivate foodborne viruses and its non-toxic, residue-free sanitation system for fresh foods makes it highly attractive to the industry. However, the lack of standard devices or protocols makes it difficult to translate these findings into meaningful applications.

Summary: This study evaluated the impact of three different cold atmospheric plasma (CAP) sources, atmospheric pressure plasma jet (APPJ), two dimension dielectric barrier discharge (2D-DBD), and nanosecond pulsed discharge (ns-pulsed), on the structure, functionality, and amino acid composition of pea protein. The plasma treatments resulted in protein denaturation, increased surface hydrophobicity, formation of soluble aggregates mainly through disulfide linkages, and changes in secondary structures. Improved surface properties, presence of soluble aggregates, and increased beta-sheet content contributed to enhanced gelation and emulsification. Significant improvement in emulsion stability was attributed to smaller droplet sizes and higher surface charge. The differences among CAP-treated samples were due to variations in plasma fluence and composition of reactive species. While all three plasma treatments showed appreciable functionalization effects, 30 min 2D-DBD (Ar + O2) treatment had negligible impact on the amino acid composition.

Summary: The relationship between energy flux, flow dynamics, and applied electrical power of a nanosecond pulsed cold atmospheric pressure plasma jet in contact with a substrate surface was investigated. The study found a transition from laminar to turbulent flow at a lower Reynolds number than conventional values, and revealed changes in energy flux with different biasing conditions.

Summary: In this study, a new method for determining both the gas temperature and the air fraction in non-thermal atmospheric helium plasmas is presented. This technique, based on UV-Atomic Emission Spectroscopy and the measurement of collisional broadening of specific emission lines, is particularly sensitive under low gas temperature conditions and suitable for diagnosing cold helium plasmas used in biomedical applications. Quantifying the air content is crucial for understanding the chemistry and clinical effects of these plasmas.

Summary: This study used a Reactive Molecular Dynamics simulation to examine the interaction between reactive oxygen species (ROS) and aflatoxin B-1 (AFB(1)) in cold atmospheric plasma (CAP) decontamination. The simulation results showed that ROS can effectively reduce the toxicity of AFB(1) by reacting with its key structures. The findings provide valuable insights for the optimization of aflatoxin degradation in industrial applications.
