The first part focus on depth-dependent XPS-measurements (XPS, synchrotron HAXPES) to obtain a concentration profile of iodine in an artificial biofilm. In the second part, NAP-XPS measurements of various bacterial samples are presented. 2018 Forschungsseminar "Ausgewählte analytische Methoden der Physik", TU Berlin Berlin, Germany 17.07.2018 2018-07-19 OPUS4-46929 Posterpräsentation Kjaervik, Marit Depth-dependent analysis of model biofilms by combining laboratory- and synchrotron-based X-ray photoelectron spectroscopy Synchrotron XPS in the soft-X-ray regime is suitable for the detection of light elements commonly found in biological samples. Various model systems of biofilms have been developed and characterised at synchrotron- and lab-based facilities. By obtaining the chemical composition at various information depths, the vertical distribution of iodine in an artificial biofilm have been determined. 2018 Tenth Joint BER II and BESSY II User Meeting Berlin, Germany 05.12.2018 06.12.2018 2018-12-10
