While the research group is currently mainly working on nanopore based sensor technology of biomolecules, for example for medical diagnostics ( and LOEWE research cluster iNAPO), the nanopore membranes were previously also investigated for filtration and separation purposes. This involved enriching organic molecules and gas molecules from mixtures and separating particles in solutions, such as blood cells from blood, aerosol particles collected in liquids or even suspended particles in beverages.

The dimensions of the pores in the films can be adjusted from diameters in the micrometer range down to the nanometer range using the ion track etching process. With diameters in the nanometre range, the separation of viruses – in the current situation of corona viruses – is also conceivable.
