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.

Multifunctional nano-sized drug carriers based on reactive polypept(o)ides

Nano-sized carrier systems find medical application to improve pharmacologic properties of bioactive agents. For many therapeutic approaches, it is important that the carrier system can stably incorporate the cargo during circulation without inducing aggregation, while cargo should ideally only be released after successful cellular uptake. These requirements have thus far only been met by chemistry […]
