At the Institute of General Electrical Engineering and Plasma Technology (AEPT) we combine our core competence of knowledge about applied plasmas with (micro-)biology. For this purpose, we have two certified Gen-S1 laboratories with basic microbiological equipment, where we can specifically investigate the direct influence of cold atmospheric or low-pressure plasmas. Our special expertise resides in the inactivation of bacterial endospores, spores of filamentous fungi, biofilms as well as typical model organisms such as B. subtilis or E. coli. Absolutely calibrated spectrometers form the basis for precise measurement methods with regard to electromagnetic radiation - e.g. in the UV-range and thus also the investigation of dose-response relationships. The multidisciplinary composition of electrical engineering and microbiology offers various methods such as scanning electron microscopy (SEM), light microscopy (LM), Fourier-transform infrared spectroscopy (FTIR), optical emission spectrometry (OES) and a portfolio of typical microbiological assays, such as airborne germ measurements, colorimetric methods for the determination of radicals and many more.
