Biofabrication and Tissue Engineering (Biofab) Facility

The Biofabrication and Tissue Engineering Facility at Karolinska Institutet (Biofab) offers a diverse range of Micro and Nanostructuring techniques for cell-based applications in the fields of life-science and medicine.

researcher in Micro and nanofabrication core facility

At BioFab, we aim to bridge the gap between engineering and biology at Karolinska Institutet and provide common grounds with respect to suitable material of use of modular design and tunable structures for biomedical purposes.

List of materials

  • Micro and nanofabrication: Glass, silicon, and polymers including different types of thermoplastics, e.g. Poly(methyl methacrylate) (PMMA), Polycarbonate (PC), Polystyrene (PS) and Teflon, thermosets, e.g. off-stoichiometry thiol-ene (OSTE), SU8 and elastomers, e.g. PDMS.
  • Bioprinting: The RegenHu R-GEN 200 bioprinter is compatible with a wide range of bioinks and materials, ranging from natural hydrogels such as alginate, gelatin, and collagen, to synthetic polymers like polycaprolactone (PCL) and polyethylene glycol (PEG). The bioprinter also supports sterile use of cell-laden bioinks, enabling the creation of complex, living tissue constructs.

  • Consultation about the proper choice of material and design with respect to the biological application
  • 3D CAD design
  • Nanofabrication via cleanroom processing
  • Surface energy patterning (tuning hydrophilicity and hydrophobicity)


Price for the in-house tool equipment: 1500 SEK/hour

Facility support: additional 1500 SEK/hour, or on collaborative bases.

For off-campus tools, prices are calculated based on each project.
