Congratulations! | We are proud to announce that our master student Ivan Knechtl received a research grant funded by the Austrian Economic Chamber-WKO Steiermark for his research on the master thesis titled 3D printed medical models used in aortic surgeries.

The scope of this master thesis is the development of 3D printed biomimetic models of the human aorta that have very similar biomechanical and pressure resistance properties when compared to the real organ. This will be achieved by combining biocomposite material and polymer science with the latest 3D manufacturing technologies.

New blood protein coagulation measurements available at IBioSys. | Control over haemostasis and coagulation analyses are essential for the assessment of blood and plasma contacting devices, and the development of anti- or procoagulant therapies. IBioSys has acquired a Stago STart Max coagulation analyser that allows for the determination of PT, APTT, fibrinogen concentration, thrombin time and others. With these methods, newly developed medicinal materials or compounds can be evaluated with respect to their interaction with blood plasma proteins.

Strong evidence has been accumulating for still poorly understood metabolic connections between lysosomal disorders and the development of Parkinson's and Alzheimer's. Based on our experience with inhibitors as enzyme stabilizers and activity enhancers for GM1-gangliosidosis and Morquio B related mutants of human lysosomal beta-galactosidase, we now want to investigate some of the complex catabolic feed-forward and feed-back cycles which may be involved in the early stages of various forms of dementia and their roots in chemical biology of the brain. Various substance classes will be evaluated emphasizing their blood-brain-barrier permeability which is a vital prerequisite for viable drugability and medication in the context under consideration.

We are happy to announce that we started to work with our new 3D Bioprinter - Gesim: BioScaffolder BS 3.2, which enables us to prepare:

  • Multi materials prints in x-y-z axis with up to four materials simultaneously at 50 µm resolutions.
  • 3D and core shell structures by extrusion composed of polymer (hydro)gels and pastes.
  • Extrusion printed 3D structures from thermoplastic materials up to 250 °C processing temperature.
  • Melt electro-writing of thermoplastic nanofibers.
  • Piezo-pipetting of life cells, reactive liquids or biomolecules.
  • UV-Photocuring of prints.
  • Working under sterile conditions.

Our partners from Institute Jožef Stefan, Department F4 under the leadership of Prof. Miran Mozetič, are working with us on the model surface peptide modification and characterization using XPS and ToF-SIMS. The cooperation includes the active participation of our students from TU Graz.

Congratulations! | To our new PhD Patrick Weber, supervised by Ao.Univ.-Prof. Arnold Stütz.
