The Junior Research Group Biosensory Surfaces is engaged in the development and characterization of novel functional layers for sensors in the life science sector (e.g. medicine, pharmacy and biotechnology).
Nowadays, biosensors are used in many different ways; for example, in clinical medicine to control blood sugar levels, for food quality control or in environmental analysis to detect potentially environmentally harmful chemicals. The core of every biosensor is the biological recognition structure, which can consist of an enzyme, an antibody, DNA or whole cells.
In the junior research group, the production of electrically conductive polymer coatings is investigated in an interdisciplinary research environment at the interface of polymer chemistry, material sciences and plasma technology. Another focus is the coupling of molecules/enzymes/proteins/cells, which can be realized by plasma-based surface modifications. The properties of the generated layers are investigated using state-of-the-art surface analysis, so that information on the layer structure and stability as a function of the coating process can be obtained. As these characteristics are directly related to the functionality as a biosensory surface, investigations on the interaction with the analyte are also carried out.
