Many papers have been published on gas plasma sterilization. They are mostly conducted by physical researchers, so microbiology and chemical aspects are significantly insufficient. By joining the biologists and chemists, gas plasma sterilization research was outstandingly advanced. The sterilization mechanism by gas plasma was not clarified until now and from the life time and some other reason...

The microbial inactivation/sterilization is an important part of our daily healthy life. This paper presents the overview on the sterilization process. Comparing the effectiveness of the sterilization agents it has been found that the short High Electric Field [HEF] pulse is the most efficient inactivation agent. This HEF pulse creates pores on the cell surface and kills the cell. Electroporati...

Objectives To assess the effect of two of the most commonly used sterilization techniques on 3D printed clinical objects. Materials & Methods The two sterilization methods used in our hospital and investigated in this paper are: Steam heat and Gas plasma. Three objects were printed and tested in this study: a tooth replica, an orthognathic final splint, a surgical cutting guide for the purpos...

As the fourth state of matter, plasma’s unique properties and interactions with other states matter offer many promising opportunities for investigation discovery. In particular, cold atmospheric plasma (CAP), operating at pressure room temperature, has remarkable potential biomedical applications through various delivery methods. These include sterilization, wound healing, blood coagulation, o...

Cold atmospheric plasma (CAP) has received great attention due to its noteworthy ability, and has also been widely studied over few decades in physics, biology and medicine. The purpose of this study is to evaluate the cold atmospheric pressure plasma effects on the proliferation of breast cancer cells. MDA-MB-231 was used for this experiment. MDA-MB-231 cells were cultured in 24-well plate and...

The use of true gas plasmas for the inactivation of microorganisms is an area of dynamic research. Many types of gases are used as a source of plasma, and different plasma production methods have been applied. The antimicrobial mechanisms of oxygen-based gas plasmas may be due to an etching effect on microbial structures, particularly bacterial endospores resulting in shrinkage. By contrast, th...
