A review over the cold plasma reactors and their applications

The cold plasma reactors are more often used in the last decades for diverse activities such as: the pollutant treatment from air or from solutions, plastic or metallic surfaces treatment, improvement of the combustion or treatments which involves biological applications. The requirements imposed to these multiple applications of the cold plasma are very different, so we have proposed to realize an appreciation of these requirements to be able to identify the “preferences” for each type of the cold plasma reactor from the multitude of the constructive variants which can be founded in the specialized laboratories today. Thereby, for surfaces treatment or for implant materials treatment to ensure the bio-compatibility with the human tissue, can be used reactors with Corona discharges, DBD or especially GlidArc. In the case of treatments of the living tissues (human tissue), targeting the blood coagulation or wound healing, the most important problem is to how the avoid the electrocution - which means that the plasma power supply parameters have to be conveniently chosen, especially the working frequency, but also the constructive type of the reactor. The preferred one would be the reactor that works with a floating potential electrode.
