BioMEMS & Sensors

The acronym „BioMEMS“ relates to „bio-electro-mechanical systems“. The BioMEMS & Sensors group performs R&D towards microsystems for microfluidic, organ-like in vitro cell culture systems (“microphysiological systems” or “organs-on-chip” systems) for applications in biological research as well as in pre-clinical drug development. Expertise comprises CAD design and multiphysics simulations of fluidic and electrical effects in micro dimensions as well as rapid prototyping and evaluation in cell culture.

In addition, the BioMEMS & Sensors group focuses on the development of electrochemical sensors for applications in medical technology (implants), biotechnology and environmental and agricultural technology. In particular, novel carbon-based nanomaterials and fluorinated membrane components are being developed and investigated towards solid contact ion selective electrodes (sc-ISE) to enable sensors with superior biocompatibility and long term stability.
