Abstract

Atmospheric pressure low power plasma jets operating in noble gases are a widespread tool in plasma medicine studies. We present experimental results obtained in one such device, which combine physical, chemical and biological measurements to assess the effectiveness in production of reactive oxygen and nitrogen species and in inactivation of Escherichia coli, a model microorganism. We proved that it exists a threshold effect on the source control parameters, defining a voltage level which has to be exceeded in order to obtain effective bacteria inactivation. This result is discussed in terms of the reactive species produced within the plasma and in treated water.

等离子体射流的综合表征：FTIR，化学研究和抗菌效果

在惰性气体中工作的大气压低功率等离子体射流是等离子体医学研究中广泛使用的工具。我们展示了在这样一个装置中获得的实验结果，该装置结合了物理，化学和生物测量来评估活性氧和氮的生产以及大肠杆菌（一种模式微生物）灭活的有效性。我们证明了它在源控制参数上存在阈值效应，定义了必须超过的电压水平，以获得有效的细菌灭活。根据等离子体和处理过的水中产生的反应物质讨论了这一结果。

期刊介绍： Publishing original papers on fundamental and applied research in plasma chemistry and plasma processing, the scope of this journal includes processing plasmas ranging from non-thermal plasmas to thermal plasmas, and fundamental plasma studies as well as studies of specific plasma applications. Such applications include but are not limited to plasma catalysis, environmental processing including treatment of liquids and gases, biological applications of plasmas including plasma medicine and agriculture, surface modification and deposition, powder and nanostructure synthesis, energy applications including plasma combustion and reforming, resource recovery, coupling of plasmas and electrochemistry, and plasma etching. Studies of chemical kinetics in plasmas, and the interactions of plasmas with surfaces are also solicited. It is essential that submissions include substantial consideration of the role of the plasma, for example, the relevant plasma chemistry, plasma physics or plasma–surface interactions; manuscripts that consider solely the properties of materials or substances processed using a plasma are not within the journal’s scope.
