We develop biomicrosystems and lab-on-a-chip devices for various diagnostic and analytic applications in medicine, biology and environmental monitoring. Internal networking provides a unique background for cross-scientific research.

Most of our biomicrosystems are based on microfluidic technologies. Microfluidic structures can be integrated with optical, electrical, and mechanical functions to realise fully integrated lab-on-a-chip solutions. We provide packaging as well as the design and realisation of measurement and user interfaces for these devices. Our expertise in tailoring molecular thin films and new antibodies ensures that we are able to serve our customers widely in this application field.


Biomicrosystems have potential to minimise required sample and reagent volumes per analysis, to reduce the analysis times, and to increase the analysis throughput. Due to the cost efficiency and small system size, biomicrosystems also enable analysis outside the laboratory. Disposable devices and point-of-care (POC) diagnostics are challenges we are currently working on.

One of our challenges is also to study biomicrosystems in new application fields. We are currently developing technology for monitoring industrial bioprocesses. We strongly believe that biomicrosystems have the potential to provide greater throughput to the screening of production organisms as well as to reduce the overall bioprocess development times.
