Low-temperature microwave microplasma for bio-decontamination

This paper presents results of the investigations of an atmospheric pressure Ar and Ar/O2 microwave (2.45 GHz) microplasmas which can be used in the biomedical applications. The microplasma in the form of a column was generated using a simple, coaxial microwave microplasma source (MMS). The gas temperature at the microplasma tip was as low as about 300 K. This makes the microwave microplasma suitable for many applications, including bio-medical. Preliminary test with Escherichia coli K-25 indicated antibacterial effect of Ar and Ar/O2 microplasmas. Streszczenie. Prezentowana mikrofalowa (2,45 GHz) mikroplazma Ar oraz Ar/O2 moze znaleźc zastosowanie w medycynie, np. przy dezynfekcji. Mikroplazme w ksztalcie kolumny wytwarza prostej konstrukcji, wspolosiowy mikrofalowy generator mikroplazmy. Temperatura na szczycie kolumny mikroplazmy jest niska, rzedu 300 K. To czyni mikroplazme uzyteczną do zastosowan w medycynie. Wstepne testy z uzyciem bakterii Escherichia coli K-25 wskazują na antybakteryjne dzialanie mikroplazmy Ar i Ar/O2.
