“…In this case, CAP can be an efficient therapy for treating burn wounds and diabetic foot ulcers [ 16 ]. In recent years, studies have shown that CAP is one of the most effective methods that can fight against pathogens, biofilms, and microorganisms [ 5 , 17 , 18 , 19 , 20 ]. Plasma reactive agents such as electrons, ions, free radicals, UV radiation, and electromagnetic fields caused by peroxidation of membrane lipids, oxidative damage to DNA, and acidification act against bacteria load [ 21 ] because the surface of microorganisms is composed of organic materials.…”

Increasing the number of resistant bacteria resistant to treatment is one of the leading causes of death worldwide. These bacteria are created in wounds and injuries and can be transferred through hospital equipment. Various attempts have been made to treat these bacteria in recent years, such as using different drugs and new sterilization methods. However, some bacteria resist drugs, and other traditional methods cannot destroy them. In the meantime, various studies have shown that cold atmospheric plasma can kill these bacteria through different mechanisms, making cold plasma a promising tool to deactivate bacteria. This new technology can be effectively used in the food industry because it has the potential to inactivate microorganisms such as spores and microbial toxins and increase the wettability and printability of polymers to pack fresh and dried food. It can also increase the shelf life of food without leaving any residue or chemical effluent. This paper investigates cold plasma’s potential, advantages, and disadvantages in the food industry and sterilization.

“…The recent outbreak of severe acute respiratory syndrome coronavirus 2, linked to frozen foods, has raised widespread concern about the safety of cold chain transportation. , However, the use of disinfection water solutions in cold chain transportation is common for cleaning nonfood items, and there are concerns about potential chemical toxicity . Cold atmospheric plasma (CAP) is one of the most efficient disinfection techniques for inactivating foodborne viruses in cold chain transportation. − The generation of CAP involves applying an electric field to a gas, resulting in the production of numerous active antiviral species, including reactive oxygen and nitrogen species (ROS and RNS) . Due to its potential as a nontoxic, residue-free sanitation technique for fresh foods and its ability to effectively eradicate foodborne viruses, the industry is highly interested in developing CAP. − Nevertheless, the practical application of CAP is hindered by the lack of uniform equipment and protocols .…”

Hydrogen-bonded organic frameworks (HOFs) are a type of porous molecular crystal consisting of multiple rigid large π-conjugated structures. They hold great potential as photosensitive antiviral materials due to their solution processability. Moreover, HOFs can easily bind to polymeric matrices, making them a flexible and green option for low-temperature antiviral materials. In this study, we fabricated a series of HOF@polymer mixed-matrix membranes (MMMs) by a solution casting technique for low temperature antiviral applications. The incorporation of HOF-101 crystals into poly vinylidene difluoride (PVDF) membranes can enhance their mechanical strength by at least 20%. The unique one-dimensional pore channels of HOF-101 enable the MMMs to have increased exposure to oxygen, providing the potential for enhanced generation of singlet oxygen ( 1 O 2 ). The 1 O 2 generated by 1 wt % HOF-101@PVDF MMMs at 263 K was observed to be more than 40% higher compared to that at 298 K. The excellent 1 O 2 generation efficiency allowed the MMMs to maintain their virucidal efficacy by more than 99% and 95% against vesicular stomatitis virus and herpes simplex virus type 1, respectively, at low temperatures.

A 3D-printed fence-surface electrode that has the potential for personalized medical application is fabricated in this study. The framework of the 3D-printed fence electrode could be any shape to fit the outline of the target. Here, the fence electrode with an area of 50 × 50 mm is made as an example to study the discharge characteristic and the affecting factors (number of bars and the curvature of the electrode). The results show that more bars of the fence electrode with the same area will have a larger discharge current and a more uniform glowing area, which is consistent with the numerical results. When introducing the human load, it will not affect the original discharge between the fence and the ground electrodes but will add discharging channels between the fence electrode and the human load when the load contacts the fence electrode. In the worst case, the maximum root-mean-square of the discharge current flowing through the human model is 5.9 mA, which is still lower than the safety thresholds. The highest temperature rise on the surface of the fence electrode is 35.226.55 °C at the condition of 15 bars for 7 kV, 3 min running. It needs a 60 s treatment for Escherichia coli and Staphylococcus aureus to get a sterilization rate of 99.99% while it needs about 180 s treatment for Pseudomonas aeruginosa to get the same rate. Finally, the procedure for designing a personalized fence-surface plasma source is illustrated and the electrodes used to fit the calf and heel are made. The discharge of the personalized fence-electrode is stable and could be used in personalized plasma medicine in the future.
