Our Skills

Amino Acids Synthesis



Development of protective groups for amino acids to enable the straight-forward synthesis of reactive polypeptides, e.g. combining stability in peptide synthesis with chemoselective reactivity in postpolymerization modification techniques.

Polymer Synthesis and Characterization


Development and detailed physicochemical analysis of various polymer architectures, e.g. (multi)block copolymers, brush polymers with homo or block copolymer side chains, star-like polymers or lipopolymers, which combine the polypeptoids polysarcosine with different polypeptide segments.

Synthesis of Functional Nanoparticles


Development of robust, scalable synthetic methods to derive functional nanoparticles with compartmentalized functionalities and precise control over size and shape to tailor particle properties to specific needs in individual applications.

Biomedical Applications



Understanding the interactions of nanoparticles with living organism to develop nanoparticle based tools for diagnosis and therapy of cancer, acute or chronic inflammations, bacterial infections or neurodegenerative diseases.
