Abstract: Plasma is a partially or totally ionized gas which occurs in nature (e.g. lightning discharge, outer space), but can be also created in the laboratory conditions. Non-thermal plasma generates free radicals of oxygen, nitrogen, high energy electrons and uncharged particles such as atoms and molecules, in aquatic and gas environment. Thus, plasma exerts its effect on both prokaryotic and eukaryotic cells. In many studies, non-thermal plasma was applied mainly to achieve the sterilization effects of e.g. surfaces and medical tools. The results obtained were largely dependent upon the applied parameters of plasma (e.g. frequency, voltage, type of gas). Non-thermal plasma can be applied in microbiology and also in medicine where it can be used to speed up wound healing process or as an effective tool in oncology.
