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 hard and software development as well as the development of new concepts for data analysis.
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 kind 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 focusses on the fields of optics, microfluidics, data analysis and experimental methods.
Jonas researches zytoscelettal filaments and cell-cell-contacts of lung epithel cell with optical and magnetic force measurements. For this he uses active and passive microrheology in an optical trap with fluorecent marked knockout cells and polystyrene beads. He measures the force and the youngs and shear modules of the cell integrines with a high speed camera and particle tracking.
