Dr. Daniel Geiger

The project CellMOUSE (Cellular Micro Optical Universal Sensing Equipment) aims to develop a novel versatile optical detection device. Its primary use case is the detection and measurement of different particles (e.g. suspended cells) at high speed and throughput of several thousand particles per second. Additionally, the whole analysis is done in real-time, so that sorting applications are feasible. The device consists of an optical sensor and a FPGA (Field Programmable Gate Array) that is used for control and analysis. My responsibilities in this project are the coordination of the hardware and software development as well as the development of new concepts for data analysis.

Dr. Tobias Neckernuß

Development of a new method for optical high-speed particle detection named CellMOUSE (Cellular Micro Optical Universal Sensing Equipment) that is capable of detecting and analyzing various kinds of particles and suspended cells. The most important parameters like size, shape, morphology, but also the mechanical properties of the cells can be determined in real-time. My work focuses on the fields of optics, microfluidics, data analysis and experimental methods.

Jonas Pfeil

The rheological properties of cells have not yet been fully explored. With the technology VELOMIR (Very Long Time Microrheology), which Jonas developed during his doctoral thesis, these properties can be measured very quickly and very precisely. This now enables the systematic measurement of cell rheology under different environmental influences.


Alexander Janik

At our institute there is an optical setup capable of determining the mechanical properties of adherent cells. A laser is deployed to stretch a cell in beam direction. The deformation is detected and yields information about its viscoelastic properties, which are crucial for the functionality of various cell types. I am working on automating the measurement and data evaluation routines and modifying the microscope setup. Thereafter, I am planning to apply the new technique, preferably in collaboration with groups from e.g. the medicine department.
