Plasma decontamination is a rapidly expanding area of modern science and engineering. An increasing number of engineers are using plasma methods for decontamination of chemical and biological agents. Plasma decontamination is effectively applied today to clean and sterilize different surfaces, high volume air and water streams, industrial exhausts, and even living tissue of animals and humans. This book provides a fundamental introduction to virtually all aspects of modern plasma decontamination, as well as the most recent technological achievements in the area. The book is segmented into four specific sections of modern plasma decontamination: (1) plasma bio-decontamination, including disinfection and sterilization of surfaces, water and air streams; (2) plasma decontamination of chemical agents, including cleaning of air, water, and industrial exhaust gases from different pollutants and especially volatile organic compounds VOC; (3) plasma treatment of living tissue, including different subjects of plasma medicine from skin sterilization to tissue engineering; (4) major electric discharges applied for the plasma-assisted decontamination of chemical and biological agents.

Non-thermal (cold) plasmas at atmospheric pressure have recently found many breakthrough applications in biology, medicine, and food security. Plasmas can efficiently kill bacteria, yeasts, moulds, spores, biofilms and other hazardous microorganisms, including potential bio-terrorism agents. They can be employed for bio-decontamination and sterilization of surfaces, medical instruments, water, air, food, even of living tissues without causing their damage. Direct or indirect plasma interaction with living cells of microorganisms or even humans enables novel bio-medical applications, e.g. treatment of skin diseases and ulcers. Plasma-enhanced blood coagulation coupled with its antiseptic properties proved success in wound healing and opens new possibilities in surgery, emergency medicine and military applications. Plasma treatment allows cell manipulations, their removal and targeted transfer into the injured area, which can accelerate wound healing. Plasma induced apoptosis (programmed cell death) of tumor cells brings forth a great potential for cancer treatment. Besides, plasma enables painless treatment of dental caries, root canal disinfection, and other dentistry applications. This book is a selection of reviewed manuscripts issuing from the NATO Advanced Research Workshop Plasma for bio-decontamination, medicine and food security held in Jasná, Slovakia, on 15-18 March 2011. It provides a comprehensive overview of the current knowledge and research activities focused at the plasma applications in areas such as bio-decontamination, water chemistry, effects on cells; biofilm inactivation, UV sterilization, and medicine, especially tissue treatment and wound healing, as well as dentistry and food security.

Our Phase I effort was meant to demonstrate that an effective technology for rapid surface sterilization of biological contaminants and neutralization of chemical warfare agents could be developed based on the application of an atmospheric pressure plasma. We used both a DC corona and dielectric barrier discharge for the sterilization tests which were conducted on a variety of substrates including metals and chemically resistant fabrics. Medically accepted biological indicator spores (Bacillus subtilis var niger and Bacillus stearothermophilus) were used to determine the effectiveness of the plasma discharge. The chemical neutralization tests were conducted using a DC corona discharge on a metal substrate contaminated with either diisopropylmethyl phosphonate or dimethylmethyl phosphonate. These simulants are of similar chemical structure to classes of chemical warfare agents like GB and Sarin. Results include decomposition of the chemical agent simulants with decomposition by-products including water, acetic acid and gases like CO2; complete sterilization in 15 minutes of some substrates contaminated with up to 105 spores over about a 1 cm2 and the concentration of the model pathogens and the surface characteristics of the contaminated substrate affects the sterilization results. A rough surface with defects is difficult to completely sterilize on short time scales

An atmospheric-pressure plasma decontamination/sterilization chamber is described. The apparatus is useful for decontaminating sensitive equipment and materials, such as electronics, optics and national treasures, which have been contaminated with chemical and/or biological warfare agents, such as anthrax, mustard blistering agent, VX nerve gas, and the like. There is currently no acceptable procedure for decontaminating such equipment. The apparatus may also be used for sterilization in the medical and food industries. Items to be decontaminated or sterilized are supported inside the chamber. Reactive gases containing atomic and metastable oxygen species are generated by an atmospheric-pressure plasma discharge in a He/O.sub. 2 mixture and directed into the region of these items resulting in chemical reaction between the reactive species and organic substances. This reaction typically kills and/or neutralizes the contamination without damaging most equipment and materials. The plasma gases are recirculated through a closed-loop system to minimize the loss of helium and the possibility of escape of aerosolized harmful substances.

Atmospheric Glow Technologies is developing an innovative mobile atmospheric plasma decon system based upon the patented one atmosphere uniform glow discharge plasma (OAUGDP) technology. This advanced system will be a deployable military protection system that will decontaminate highly toxic chemicals and microorganisms on sensitive equipment, personnel protective equipment, and aircraft, vehicle, and shelter interiors. Phase I efforts demonstrated feasibility of the system in the neutralization of chemical warfare simulants (99.3% reduction). Phase II efforts will extend studies to biological warfare agents including spores, building upon the proven efficacy of the OAUGDP against a wide range of microorganisms. Future work will involve optimizing the system for recirculation of the airflow and air cooling. Studies are currently underway to determine the concentration of atmospheric plasma produced active species as well as the extent of chemical and biological degradation achieved. The system will also be tested for materials and device compatibility as well as neutralization studies of actual chemical and biological warfare agents.

Cold atmospheric plasma (CAP) generators have been actively developed as a new device for medical treatment. The applications of plasma treatment include 1) disinfection, sterilization, and decontamination, which inactivates or kills bacteria, fungi, viruses and spores; 2) bleeding control, which coagulates blood swiftly; 3) wound healing, which shortens the healing period and benefits the regeneration of the epithelization of tissue to avoid scar formation; etc.Biomedical applications of CAPs are explored via either in-vitro assays, or in-vivo tests using pigs as animal models; tests include sterilization of oral pathogens and biofilm, decontamination of biological warfare agent, blood clotting and rapid control of active life-threatening hemorrhage, and post-operative observation of wound healing after plasma treatment. The conventional approaches in each application are first introduced, then the advantages of plasma treatments are discussed and demonstrated by the test results. The mechanisms of CAPs' biocidal effect, blood clotting effect, and wound healing effect are presented and discussed.
