Non-thermal atmospheric-pressure plasma, also named cold plasma, is defined as a partly ionized gas. Therefore, it cannot be equated with plasma from blood; it is not biological in nature. Non-thermal atmospheric-pressure plasma is a new innovative approach in medicine not only for the treatment of wounds, but with a wide-range of other applications, as e.g. topical treatment of other skin dise...

the direct conversion of methane to c2 hydrocarbons, in a quartz tube reactor enforced by a dc corona discharge, was investigated at atmospheric pressure. the process was carried out in the presence of metal oxide catalysts of mn/w/sio2, mn/w/sio2 (tetraethyl orthosilicate, teos), and mn/w/cnt (supported on carbon nanotubes). the total yield to c2 hydrocarbons in the presence of metal oxide cat...

PURPOSE Autoclaves and UV sterilizers have been commonly used to prevent cross-infections between dental patients and dental instruments or materials contaminated by saliva and blood. To develop a dental sterilizer which can sterilize most materials, such as metals, rubbers, and plastics, the sterilization effect of an atmospheric pressure non-thermal air plasma device was evaluated. MATERIAL...

It was presented that various types of non-thermal atmospheric pressure plasma sources operated with low frequency(~kHz) or microwave frequency feeding argon or helium gas, or in the ambient air could be used for the treatment of cancer cells, sterilization, tooth whitening, and blood coagulation. The antibody-conjugated GNPs enhanced to kill cancer cells exposed to plasmas. The plasmas treatme...

Non-thermal atmospheric pressure plasma has attracted great interest due to its multiple potential biomedical applications with cancer treatment being among the most urgent. To realize the clinical potential of non-thermal plasma, the exact cellular and molecular mechanisms of plasma effects must be understood. This work aimed at studying the prostate cancer specific mechanisms of non-thermal p...

This paper reports on the selection of insulating material types in a developed atmosphericpressure non-thermal plasma jet (ANPJ-II) device which was operated previously in our laboratory based on the minimum erosion area of the insulator’s nozzle. Three identical insulator groups used in our experiment include; Teflon insulator material with different thicknesses of 1.5 mm and 2 mm respectivel...

Objectives. Antimicrobial activities of non-thermal atmospheric plasma-treated liquids on various bacterial and fungal strains in their planktonic and biofilm forms have been widely reported. Since most of the plasmatreated liquids are water based, they might be washed off certain surfaces and they cannot be applied for the infections of respiratory tract. In the present study we have tested an...
