| Description | The paper is focused on comprehensive diagnostics and biomedicine applications of surfatron microwave (2.45 GHz) discharge. Discharges with reactive gas components (N2 or O2) are in our highest interest because of their next technological applications. In the first part basic plasma parameters are investigated by means of single and double Langmuir probe techniques at wide range of pressures in both, cw and pulsed, discharge regimes. Rotational temperature, discharge composition and intensity development of particular emission lines were revealed by means of optical emission spectroscopy. The second part of the contribution is focused on experimental applications of surfatron plasma - plasma-based sterilisation and surface activation of polyethylene surface. Sterilisation experiments of tested micro-organisms Escherichia coli and Staphyloccus epidermis were done. Germicidal effect of particular discharges was considered after discharge application on defined bacterial cultures. |
