<unk>  is an emerging field that combines<unk>  physics, life sciences and clinical medicine. It is being studied in disinfection, healing, and cancer. Most of the research is in vitro and in animal models. It uses ionized gas (physical<unk>  for medical uses or dental applications.<unk> , often called the fourth state of matter, is an ionized gas containing positive ions and negative ions or electrons, but is approximately charge neutral on the whole. The<unk>  sources used for<unk>  are generally low temperature<unk> s, and they generate ions, chemically reactive atoms and molecules, and UV-photons. These<unk> -generated active species are useful for several bio-medical applications such as sterilization of implants and surgical instruments as well as modifying biomaterial surface properties. Sensitive applications of<unk> , like subjecting human body or internal organs to<unk>  treatment for medical purposes, are also possible. This possibility is being heavily investigated by research groups worldwide under the highly-interdisciplinary research field called<unk> '.
