Biologized Materials and Structures


© Fraunhofer IKTS

Freely following the guideline “working with the achievements offered by Mother Nature”, the IKTS group “Biologized Materials and Structures” develops

  • biomimetic, personalized bone replacement materials,
  • bioinspired mineralization processes,
  • Living (Building) Materials (LBM) as well as
  • sustainable “green manufacturing” technologies (i.e., cold sintering processes) and provides
  • expertise regarding structural engineering processes, Metal-Organic-Frameworks (MOFs) and scientific state-of-the-art.

The working group "Biologized Materials and Structures" offers its expertise to its research partners and customers in joint projects. We are glad to develop new ideas with you and jointly open up new subject areas and industrial applications in both feasibility studies and specific product developments.


Research and cooperation offer


  • Patents on Freeze Foaming and porous bone replacement materials/material mixtures
  • Biocompatible and biodegradable bone replacement materials
  • Personalized implant structures
  • Research in bioceramics and biopolymers in combination with cellular materials
  • Bioinspired material synthesis
  • In-situ mineralization and biologization
  • Development of LBM (Living Building Materials) within and outside biomedical application fields e.g., as sustainable building and construction materials
  • Process development of Freeze Foaming, near-net-shape forming techniques and bio-based additive manufacturing incl. (inline) material diagnostics
  • Structural design and testing of Metal-Organic-Frameworks (MOFs), e.g., for gas exchange/storage/substance separation within and outside biomedical applications.
