Summary/Accomplishments (Outputs/Outcomes):

Results showed that the preliminary device can produce singlet oxygen safely, and can destroy biotoxin simulant at up to a 4-log reduction, without process optimization. The measured temperature of the cold plasma effluent was less than 10°C above ambient temperature. These results, and analysis of the power and equipment required, suggest that a lightweight, small backpack-mounted, low-power device is feasible and can be fabricated during Phase II.


Through an innovative combination of microwave technology coupled with compressible fluid dynamics, the Phase I research project resulted in the development of a safe, effective, inexpensive, and easy to use decontamination system. The availability of a compact cold plasma device could have a large impact on decontamination needs within the military. It also may have the potential for multiple applications in the private sector, beginning with museums, historic buildings, and important government and civilian buildings. Completion of the project could lead directly to commercial sterilization equipment for the food and health care industry.
