Biofab Core Facility - our offer

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