Abstract A radio-frequency driven plasma jet in annular geometry coupled with an aerosol injection into the effluent is proposed for controllable reactive oxygen species (ROS)/reactive nitrogen (RNS) production and delivery on biological targets context of medicine, e.g. wound care. The role aqueous modulating investigated by combining physical chemical analytics. Optical emission spectroscopy, electron paramagnetic resonance a biochemical model based cysteine as tracer molecule have been...
One of the driving forces behind development cold plasma sources at atmospheric pressure is an application in biomedical field.In this respect, radio-frequency (RF) jets are particular importance due to possible safe operation on humans and a generation high amount reactive species.For reason, we designed RF jet co-axial geometry with possibility aerosol introduction, where its characteristics were evaluated by electrical diagnostics, optical emission, laser scattering spectroscopy.The...
Abstract Non‐thermal plasmas operating at high pressure attract increasing attention for a variety of applications as an alternative to conventional chemical processes. In this study, atmospheric direct current non‐self‐sustained discharge in nitrogen is investigated source non‐thermal plasma capable glow regime. The sustained between internal ionization and metal or liquid electrode studied by electrical diagnostics well spectroscopy methods. work focused on the determination properties...
Abstract The quest to employ cold plasma sources at atmospheric pressure in polymer processing has emerged as a potent driving force behind their development. Atmospheric operation of jets provides potential cost reductions well easier handling and maintenance. In addition, unique advantage remote allows the substrate be placed outside source boundaries. This latter feature makes it process complex three-dimensional objects integrate into existing production lines. Although conventional jet...
The possible benefits of an atmospheric pressure plasma jet skin treatment have been tested in vivo on mouse skin. Many studies conducted vitro cells, but only a few where, due to the complexity biological system, can cause severe damages. For this reason, we investigated how kHz generated that is known inflict damage interacts with and explored reduce damage. First, focus was exploring effects formation different gases inclinations. results pointed perpendicular orientation He as most...
Cold plasmas have found their application in a wide range of biomedical fields by virtue high chemical reactivity. In the past decades, many attempts been made to use cold wound healing, and within this field, studies focused on plasma-induced cell proliferation mechanisms. work, one step further has taken demonstrate advanced role plasma healing. To end, simultaneous ability induce permeabilize treated cells examined current study. The driving force was advance healing effect with drug...
The antibacterial and cell-proliferative character of atmospheric pressure plasma jets (APPJs) helps in the healing process chronic wounds. However, control plasma-biological target interface remains an open issue. High vacuum ultraviolet/ultraviolet (VUV/UV) radiation RONS flux from may cause damage a treated tissue; therefore, controlled interaction is essential. VUV/UV emission argon APPJs with aerosol injection effluent focus this research. effect on studied by fluorescent capable...
Plasma jets are extensively used in biomedical applications, particularly for exploring cell viability behaviour. However, many experimental parameters influence the results, including jet characteristics, secondary liquid chemistry and protocols used, slowing research progress. A specific interest of presented was skin behaviour under a non-thermal kHz plasma jet—a so-called cold jet—as topical treatment. Our focused on vitro mouse direct treatment with argon as an operating gas. The...
Outside Front Cover: An atmospheric pressure non-self-sustained glow discharge is investigated as an alternative source for conventional chemical processes. Optical emission spectroscopy and Rayleigh scattering were applied to obtain vibrational, rotational translational temperatures. In addition, electron density temperature estimated based on experimental data. impact of water presence plasma physical properties, a difference between temperatures, N2 excitation pathways are discussed in...
In the last decades, atmospheric pressure plasma jets (APPJs) have shown a lot of potential as an alternative to conventional methods in autoimmune disease treatments and wound healing[1]. Their advantage is assigned simultaneous generation ions, metastables, radiation, reactive oxygennitrogen species, [2]. Among others, AAPJs operating Ar are considered high commercial medicine due relatively low operational costs. Nevertheless, UV radiation from argon excimers <inf...
