Summary: The main objective of this study was to design a large-scale cold atmospheric plasma brush (LSCAPB) that can produce a perfectly homogenous large area capable of inactivating Gram-positive and Gram-negative bacteria commonly implicated in food infections. The study demonstrated that the LSCAPB had a significant inactivation effect on bacteria, with the best results obtained at 25 kV voltage. This research indicates that LSCAPB can be one of the most efficient methods for the inactivation of different types of bacteria.

Summary: This study investigates the antibacterial effects of liquid discharge cold plasma (LDCP) on Enterococcus faecalis (E. faecalis) planktonic cultures and root canal biofilms. The results show that LDCP treatment has a significant antibacterial effect on both planktonic E. faecalis and biofilms, surpassing the efficacy of 0.2% chlorhexidine treatment. This work suggests the potential application of liquid discharge plasma devices in root canal treatment.

Summary: The efficiency of simultaneous treatment of cold atmospheric pressure plasma jet (CAP) and hydrogen peroxide (H2O2) was studied for bacterial disinfection. The combination of CAP with H2O2 showed dramatic synergistic effects in killing bacteria by enhancing reactive species transportation and intracellular oxidation. The non-toxic byproducts of CAP and H2O2 make their combination a promising candidate for clinical applications.

Summary: Excessive or persistent infection impedes chronic wound healing. Antiseptics may not target all bacteria and can be cytotoxic to granulation tissue, impairing repair. Non-thermal gas atmospheric pressure plasmas provide an ideal approach for topical wound disinfection by accessing irregular cavities and fissures and killing bacteria diffusively. A novel non-thermal plasma brush device has been developed for clinical application in disinfecting oral and wound bacteria, with in vivo studies showing improved wound healing in biofilm-infected wounds treated with Ar + N-2 plasma.

Summary: Paper-based analytical devices (PADs) have become popular for their cost-effectiveness, portability, and eco-friendly features in rapid bacteria detection and biotoxicity measurement. Through colorimetric response and smartphone recording, metabolic differences among bacteria can be detected in 10 minutes, while the toxicity difference between two chlorophenols to bacteria can be identified in 30 minutes.

Summary: Enterococci are a diverse group of Gram-positive, lactic acid bacteria that can be found in various environments, including fermented foods, posing a health threat and hospital-acquired infections due to antimicrobial resistance. Bacteriophages are ideal biotechnological weapons for controlling bacterial growth, but require a combination of phages with different host ranges. The isolation of Enterococcus faecalis-infecting bacteriophages from cheese samples adds to the potential arsenal for bacteriophage-based biocontrol of harmful E. faecalis populations.

Summary: A cold atmospheric plasma (CAP) patch was developed for the treatment of skin diseases, especially psoriasis. The patch induces the opening of calcium channels in keratinocytes and generates ROS/RNS, improving psoriatic symptoms. It can be used as a combination therapy with existing drugs, reducing side effects.

Summary: Skin diseases can be categorized into infectious diseases, non-infectious inflammatory diseases, cancers, and wounds. The underlying causes include microbial infections, autoimmune responses, abnormal cellular proliferation or differentiation, and excessive production of inflammatory factors. Cold atmospheric plasma (CAP), as an innovative and non-invasive therapeutic approach, has shown promising efficacy in dermatology by inhibiting infections, promoting wound healing, suppressing cancer growth, and improving psoriasis or vitiligo lesions. This review summarizes recent advances in CAP therapies for various skin diseases and proposes future strategies for increasing effectiveness and expanding clinical indications.

Summary: In the driving circuit, the phase difference of signals from two channels are 180 degrees. Moreover, when the duty cycle is set at 40%, it can ensure sufficient pulse width modulation response time. In the protection circuit, when over-current occurs, an intermittent output signal is automatically sent out. Furthermore, the over-current response time can be controlled independently.

Summary: Due to the large Gibbs free energy of metal telluride for hydrogen generation, tellurium (Te) based materials are rarely reported as catalysts for overall water splitting. However, through a facile hydrothermal method, stacked flower-like NiTe-NiSe nanosheets have been engineered, bringing transition metal telluride closer to application in the field of clean and renewable energy. The hollow flower-shaped catalyst assembled with nanosheets significantly increases the active surface area, resulting in low overpotentials for hydrogen and oxygen evolution processes.
