Our team is physically based at the KIT Campus North and funded by the German Ministry of Education and Research. Our group is jointly hosted by the Institute of Toxicology and Genetics and the Institute of Chemical Technology and Polymer Chemistry.
We aim at developing novel hybrid nanostructured surfaces and colloids by combining polymers and various biomolecules. We use organic chemistry (basic, modular ligations, photochemistry), modern techniques of macromolecular engineering (e.g., activation-deactivation radical polymerization, living ring-opening polymerization), modification of biomolecules (peptide synthesis, protein modification), and self-assembly principles to achieve our aims. We seek fundamental understanding or applications in the areas of protein-protein interaction, biocatalysis, and targeted delivery.
We are also very interested in novel water-soluble biocompatible polymers, advanced photochemical nanopatterning techniques, and macromolecules and materials that can be chemically or conformationally re-arrange following stimulation by light, temperature, or pH. We work in close collaboration with other chemists but also with biologists, physicists, and engineers.
For an overview of past and current projects, please refer to the Research section and the Publications section.
The great work of Ana, who was a postdoc in the group, on the simplified synthesis of single-enzyme nanogels and their characterization, was just published online in Chemical Science. We are very excited! Thanks to Prof. Uli Nienhaus and his postdoc, Andrei Kobitski, for the great collaboration!

Guillaume just finished his conference tour after 8 days in Japan. He attended the APME2015 conference in Yokohama where he orally presented the work of Ana on enzyme encapsulation and had two posters on the studies of Hatice (orthogonal thiol-based chemistries) and Tanja (photoreactive 3D microstructures). This was followed by some sightseeing in Yokohama, Kamakura, and Tokyo. His impressions: extremely friendly and respectful people, great food (Tuna!!! Noodles!!! Yakiniku!!! Whiskies!!!), and fascinating cities and historical sites.
Before that, he also attended the Kármán conference, a very high-level – yet intimate – symposium in Vaals (Netherlands) organized by Prof. Martin Moeller (DWI-Leibniz Aachen). He presented the work of Ana with a poster on the encapsulation of enzymes.
The group participated to the annual excursion of the ITG in the region of Rhodt and Rietburg in the beautiful wine region of Palatinate. We spent a nice day with hiking in the rain to the Rietburg castle, visiting the Villa Ludwigshöhe, enjoying a nice lunch with the finest German specialties (Spätzle and Leberknödel), and attending a wine tour/tasting at the Gries winery. Despite the terrible weather, it was fun! Visit our Pictures section.
