We are a young research group located in the research building SupraFAB working at the interface of organic, macromolecular and biological chemistry. Our goal is the development of tailor-made oligo- and polymers with defined charged sequences that interact with relevant biomolecules or biosystems - especially cell membranes and glycosaminoglycans that can be present both on cell surfaces or as signaling molecules in solution. Inspired by simple organic reactions as well as techniques from polymer and peptide chemistry, we want to generate sequence-defined, charged, multifunctional synthetic structures and study their interactions with mentioned biosystems, unraveling structure-activity relationships on a level of detail that is not possible using conventional, polydisperse polymers.
