introduction cold plasma is a self-sterilized, painless, and non-contact method in surgeries. these properties allow it to be applied to the living tissues and heat-sensitive parts. the aim of this study was to design a new cold plasma producer device and evaluate the effects of cold argon plasma on decreasing the coagulation time of blood drop in vitro and that of the injured liver blood in vi...

Plasma sterilization offers a faster, less toxic and versatile alternative to conventional sterilization methods. Using a relatively small, low temperature, atmospheric, dielectric barrier discharge surface plasma generator, we achieved ≥ 6 log reduction in concentration of vegetative bacterial and yeast cells within 4 minutes and ≥ 6 log reduction of Geobacillus stearothermophilus spores withi...

Cold atmospheric plasma (CAP) is an ionized gas where the ion temperature is close to room temperature as opposed to typical high-temperature laboratory plasmas. It can be carried out in the presence of Helium (He) with a high voltage. CAP is composed of various electrons, positive/negative ions, reactive oxygen species (ROS), reactive nitrogen species (RNS), radicals, excited molecules, energe...

introduction the aim of this study was toinvestigate the sterilization potential of atmospheric pressure plasma jet (appj) and interactions of this technology with double-stranded dna using the polymerase chain reaction (pcr) and single-strand conformation polymorphism (sscp) techniques. materials and methods the plasma jet was produced through a high voltage sinusoidal power supplyusing a mixt...

There are few suitable techniques available to sterilize biodegradable polyester three-dimensional tissue engineering scaffolds because they are susceptible to degradation and/or morphological degeneration by high temperature and pressure. We used a novel polyllactide-co-glycolide) scaffold (Osteofoam) to determine the optimal sterilization procedure--i.e. a sterile product with minimal degrada...

the present paper explores the impact of an on-board hydrogen harvesting system (fuel reformer) on the overall efficiency of a fuel-cell powered vehicle. various methods of hydrogen production for automotive applications have been discussed first. as the hydrogen production is one of the major challenges for application of proton exchange membrane (pem) fuel cells, especially in vehicular indus...

Traditional disinfection methods against pathogens have numerous shortcomings, and inventive like cold plasma are required for virus inactivation. Here, an atmospheric pressure 13.56 MHz radio-frequency hollow cathode (RF–HC) device has been used to build a sterilization device, its virucidal activity is assessed P2 bacteriophage, model surrogate pathogenic viruses. The heart of this contains t...
