Biopolymer Coatings and Films

What we are doing…
    …is to make macro/micro/nanopatterned biopolymer thin films using a wide range of techniques.
    …is to exploit these structures to include additional functionality into the films.
    …is to explore the interactions of such films with biomolecules such as proteins.
    …is to investigate different processing technologies to tailor the properties of such films.



Who is doing that…
      …Gundula Teichert
      …Stefanie Müller


Who pays for it…
