“…Based on these results, the Physics and Electronics Directorate of the US Air Force Office of Scientific Research (AFOSR) funded a proof of principle research program in 1997 and supported such research for a number of years. The results from this research program were widely disseminated in the literature, including in peer-reviewed journals and conference proceedings, therefore attracting the attention of the plasma physics community to new and emerging applications of low temperature plasma in biology and medicine [2][3][4][5][6][7][8]. The goals of the AFOSR program were to apply low temperature plasmas (LTP) to treat the wounds of injured soldiers and to sterilize/disinfect both biotic and abiotic surfaces.…”

This mini review is to introduce the readers of Plasma to the field of plasma medicine. This is a multidisciplinary field of research at the intersection of physics, engineering, biology and medicine. Plasma medicine is only about two decades old, but the research community active in this emerging field has grown tremendously in the last few years. Today, research is being conducted on a number of applications including wound healing and cancer treatment. Although a lot of knowledge has been created and our understanding of the fundamental mechanisms that play important roles in the interaction between low temperature plasma and biological cells and tissues has greatly expanded, much remains to be done to get a thorough and detailed picture of all the physical and biochemical processes that enter into play.

“…[1][2][3] Highly functional surfaces can be produced on materials such as plastics and polymers, 4 including woven and unwoven textiles. 5 Other applications of atmospheric plasmas include the purification of water, 6 the sterilization of surgical instruments, 7,8 and localized treatment of biological samples. 9 The plasmas of current interest range from those with large surface areas and substantial output powers, including surface barrier devices, to much lower power devices suitable for precision medical applications such as microsurgery.…”

Fractional number density measurements for a rf plasma "needle" operating at atmospheric pressure have been obtained using a molecular beam mass spectrometer ͑MBMS͒ system designed for diagnostics of atmospheric plasmas. The MBMS system comprises three differentially pumped stages and a mass/energy analyzer and includes an automated beam-to-background measurement facility in the form of a software-controlled chopper mechanism. The automation of the beam modulation allows the neutral components in the plasma to be rapidly and accurately measured using the mass spectrometer by threshold ionization techniques. Data are reported for plasma generated by a needle plasma source operated using a helium/air mixture. In particular, data for the conversion of atmospheric oxygen and nitrogen into nitric oxide are discussed with reference to its significance for medical applications such as disinfecting wounds and dental cavities and for microsurgery.

“…Several mechanisms were initially suspected for destruction of bacteria and spores: reaction with chemically reactive species (like free radicals), electrical interaction and sputtering with charged particles, and exposure to UV radiation. Inactivation of bacteria by means of chemically reactive species has been observed by many groups [1][2][3][4][5][6][7][8][9][10][11][12][13]. Atomic oxygen, ozone, hydroxyl, peroxyl, and NO x radicals are some of the species with demonstrated effects on cells [4].…”

Decontamination of a rotating cutting tool during operation by means of atmospheric pressure plasmas

et al. 2010

The decontamination of a rotating cutting tool used for slicing in the meat industry by means of atmospheric pressure plasmas is investigated. The target is Listeria monocytogenes, a bacterium which causes listeriosis and can be found in plants and food. The non-pathogenic species, Listeria innocua, is used for the experiments. A rotating knife was inoculated with Listeria innocua. The surface of the rotating knife was partly exposed to an atmospheric pressure dielectric barrier discharge operated in air, where the knife itself served as a ground electrode. The rotation of the knife ensures a treatment of the whole cutting tool. A log 5 reduction of Listeria innocua is obtained after 340 s of plasma operation. The temperature of the knife after treatment was found to be below 30°C. The design of the setup allows a decontamination during slicing operation.
