“…coli mutants not as contaminants but as sensors of oxygen plasma species thus providing an additional line of information in the current quest for a full understanding of microplasma decontamination 219. It is worth mentioning the importance of the studies that aim to identify and understand the biological signatures of microplasma impact 220–224. It is conceivable that the combination of the physical mechanisms (e.g., identification and quantitative evaluation of biocidal plasma agents) and the biological mechanisms (e.g., identification and confirmation of plasma‐induced biological events) will be central to the future success of microplasma decontamination.…”

“…Finally, the scope of microplasmas for biomedical applications goes beyond decontamination and sterilisation. For example, microplasmas have been used for blood coagulation217, 225 and tissue ablation226 in surgery, DNA extraction,227 apoptosis induction of cancer cells,9, 228 cell manipulation for cell adhesion control229 and DNA transfection,230 and more recently wound healing 216. These are at varying stages of their development, each of which can benefit significantly from a fundamental understanding of particle kinetics of microplasmas and each of which offers stimuli to the advancement of fundamental microplasma science.…”

Thanks to their portability and the non‐equilibrium character of the discharges, microplasmas are finding application in many scientific disciplines. Although microplasma research has traditionally been application driven, microplasmas represent a new realm in plasma physics that still is not fully understood. This paper reviews existing microplasma sources and discusses charged particle kinetics in various microdischarges. The non‐equilibrium character highlighted in this manuscript raises concerns about the accuracy of fluid models and should trigger further kinetic studies of high‐pressure microdischarges. Finally, an outlook is presented on the biomedical application of microplasmas.

“…The cold atmospheric pressure plasma emits several potentially bactericidal factors, such as charged particles, reactive oxygen species, reactive nitrogen species, UV photons, and intense electric fields 8–10. Though the study of plasma decontamination is expanding,11–22 the intricacy and the high reactivity to any organic materials of the plasma sources have so far made it difficult to prove the inactivation mechanism of microorganisms. To understand the inactivation mechanism will be to find out interactions between donor plasma factors and recipient biological components whose damage leads to death of the microorganisms.…”

Inactivation mechanisms of plasma treated microorganisms are still major subjects. We have developed a biological assay which evaluates in vivo DNA damage of the viruses treated with non‐thermal atmospheric pressure plasma in air. Different doses of the plasma were applied to wet state of λ phage particles under neutral pH and near the room temperature. From each sample of treated λ phages, DNA was purified and subjected to in vitro DNA packaging reactions. Survival curves of the re‐packaged phages showed an extremely large D value (D = 25 s) compared to the previous D value (D = 3 s) obtained from the survival curves of the treated phages. The results indicate the evidence that DNA damage hardly contributed to the inactivation.

“…Much in applied research on high voltage engineering of plants and biological objects has been made since the 1980s. A large number of applied investigations have been carried out on sterilization by plasma‐chemical reactions produced by pulsed discharges and on electroporation caused by pulsed‐electrostatic force . The research area is expanding not only into medicine but also into other fields.…”

SUMMARY This paper presents an experimental study of control of the germination of Arabidopsis seed with a barrier discharge produced by polarity‐reversed voltage pulses. 100 ns‐width polarity‐reversed pulses were applied to the seeds between plane electrodes covered by glass barriers. The electrode configuration allowed barrier discharge propagation along the seed surface at a relatively low voltage. After the discharge treatment, the seeds were incubated for 2 or 3 days to measure the germination rate. The relationships between the cumulative input energy density into the plasma and the germination rate were investigated. The germination rate was significantly reduced at 20 J/cm3. However, it increased at cumulative energy densities up to 50 J/cm3 and then decreased again on further energy input. These results suggest a superposition of two effects, stimulation and inhibition, of the discharge treatment on the germination of Arabidopsis seed. The results of Evans Blue dyeing of the discharge‐exposed seeds indicate that necrosis of the seed coat is caused by the discharge treatment.
