Multi-parameter assessment of spheroids and bioprinted microtissues

About this line of research

Bioprinting and the use of numerous biomaterials require the development of online and continuous monitoring tools, reporting on cell health, death, differentiation and thus predicting the overall quality, reproducibility and long-term stability of bio fabricated tissues. Currently, we focus on optimising multi-parameter O2 imaging in bioprinted constructs, organoids and differentiating homo- and heterocellular spheroids.

We employ multiplexing in spectral and luminescence lifetime domains and aim at expanding the biosensor probes toolkit, e.g. by utilising staining of the cells, use of genetically encoded proteins, functional autofluorescence and labelling of extracellular matrix components.

Here we also collaborate with research groups who design and model microfluidic chips as well as develop innovative biomaterials and biosensors.
