“…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.

“…This parameter is the time required to reduce an original concentration of micro-organisms by 90 % (one log 10 reduction) and is expressed in the unit of time. Single-slope survival curves have been observed in atmospheric pressure plasma sterilization by Herrmann et al (Herrmann et al, 1999), Laroussi et al (Laroussi et al, 2000) and Yamamoto et al (Yamamoto et al, 2001) and an example of such a single-slope curve is presented in Figure 1.

“…Kelly-Wintenberg et al (Kelly-Wintenberg et al, 1998) and Laroussi et al (Laroussi et al, 2000) employed an atmospheric pressure glow discharge (DBD) for the inactivation of E. coli, Staphylococcus aureus and Pseudomonas aeruginosa. In contrast to the vacuum plasmas, the D-value of the observed second slope (D 2 ) was smaller than the D-value of the first slope (D 1 ) in these plasma systems.…”

“…For sterilization, there are reports on the inactivation of bacteria, such as Escherichia coli [5,6], Micrococcus luteus [7], and Staphylococcus aureus [8], using atmospheric-pressure plasma and on the disruption of Bacillus subtilus spores [9,10] and Bacillus atrophaeus spores [11,12]. For medical applications, it was reported that the irradiation of mammalian cells with atmospheric-pressure plasma caused their necrosis [13] or apoptosis [14] depending on the irradiation conditions.…”

The two-dimensional concentration distribution of hydrogen peroxide (H2O2) generated by atmospheric-pressure argon (Ar) plasma jet irradiation was semiquantitatively determined using H2O2 test strips. An Ar plasma jet was generated with different applied voltages (5-10 kV) and Ar gas flow rates (3-10 L/min) and was irradiated onto the H2O2 test strips at different irradiation distances (2-40 mm) and irradiation times (5-30 s). The shape of the distribution of H2O2 concentration depended on the combination of the applied voltage, gas flow rate, and the irradiation distance and was classified into four types: circular, double-circular, ring-shaped, and double-ringshaped. A circular distribution was observed for irradiation distances of ≥30 mm and a double-circular distribution was observed for irradiation distances of 10-20 mm. When the irradiation distance was ≤5 mm, a ring-shaped distribution was observed for applied voltages of ≤6 kV and a double-ring-shaped distribution was observed for applied voltages of ≥7 kV.
