Molecular Effects of Atmospheric Pressure Plasma Jet on the Double-Stranded DNA
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...
متن کاملA microfabricated atmospheric-pressure microplasma source operating in air
An atmospheric-pressure air microplasma is ignited and sustained in a 25μm wide discharge gap formed between two co-planar gold electrodes. These electrodes are the two ends of a microstrip transmission line that is microfabricated on an Al2O3 substrate in the shape of a split-ring resonator operating with a resonant frequency of 895 MHz. At resonance, the device creates a peak gap voltage of ∼...
متن کاملExternal Transverse Direct Current Magnetic Field Effect On Optical Emission Of a Non-Thermal Atmospheric Pressure Argon Plasma Jet
An experimental study of plasma jet at atmospheric pressure was carried out to examine the influence of external transverse magnetic field on it. A magnetic field was applied to the jet in atmospheric pressure by means of a pair of coils, same Helmholtz coil configuration. It was applied transverse to the jet flow. The strength of the direct current magnetic field was 00.057 Tesla between the t...
متن کاملOn plasma parameters of a self-organized plasma jet at atmospheric pressure
Electron temperature and electron concentration in the active zone of a miniaturized radio frequency (RF) non-thermal atmospheric pressure plasma jet in argon have been determined using two independent approaches: the spectroscopic measurement of the broadening of Balmer Hβ and Hγ lines and a time-dependent, spatially two-dimensional fluid model of a single discharge filament. The plasma source...
متن کاملInactivation of Staphylococcus aureus and Enterococcus faecalis by a direct-current, cold atmospheric-pressure air plasma microjet☆
OBJECTIVE A direct-current, cold atmospheric-pressure air plasma microjet (PMJ) was performed to inactivate Staphylococcus aureus (S. aureus) and Enterococcus faecalis (E. faecalis) in air. The process of sterilization and morphology of bacteria was observed. We wish to know the possible inactivation mechanisms of PMJ and explore a potential application in dental and other temperature sensitive...
