Life Science and Bioprocesses

Polymeric materials with biological functions

Nature has been developing and optimizing biological systems for millions of years. We use these proven mechanisms in the research division of Life Science and Bioprocesses to expand the range of polymer functionality. Our focus is on integrating new biological functions into polymer materials.  

In the department of Functional Protein Systems/Biotechnology, polymer research is combined with biotechnology in a unique way. Functional biobased building blocks are produced and implemented using chemical, physical and biotech methods. Interactive colloidal systems are also developed.

The department of Biomaterials and Healthcare unites polymer research, nanotechnology and interfacial chemistry to develop new, high-tech materials for medical technology through to application maturity.

Our research topics

Our activities in the research division of Life Science and Bioprocesses span a wide range of application fields. We develop materials and key substances, for example, for biotechnology, medical products, pharmaceuticals and cosmetics, as well as for environmental- and nanotechnologies.

In addition to the traditional research fields, our research and development concentrates on biomaterials and hydrogels, implants, bioactive surfaces, sensors and biotech processes. Microbiology testing and testing using primary cells and cell lines deepen the scope of our R&D capabilities.

Focus is also placed on the synthesis of polymers and biohybrid materials, the production of ultra-thin membranes and the biofunctionalization of surfaces.

Our developments in biotechnology are implemented on a lab-scale and scaled up to pilot plant-scale. The utilization of renewable raw materials in the production of biopolymers and their use as a fermentation substrate play a key role in this regard.
