During October and November 2021 I have been visiting NMI in Tübingen for a period of five weeks. The aim of the secondment was to learn about fabrication of microfluidic chips, and transfer a concept for a hydrogen peroxide sensor to microfluidics. I have felt very welcome at NMI by not only the two ESRs employed at NMI, but the entire working group and staff. In my spare time I have been sightseeing in both Tübingen and Stuttgart, hiking during sunny days (and one rainy), and went bouldering. All together with some of the cool people from the working group.
