Daniel investigates the behaviour of migrating cells on microstructured substrates. They are based on photoreactive polymers that change during light exposure. Therefore, the surface properties are changed locally. The main goal of the work is deeper understanding of the interplay between substrate and cell duringe migration.
Tobias builds up a new device, a so called optical adherent cell stretcher. To this end he tries to adopt the principle of a conventional optical stretcher to develop a setup which allows both, to stretch adherent cell with laser light and to investigate the deformation via a microscope.
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.
