Munich Multiscale Biofabrication Network


We fabricate artificially designed micro-environments to culture and probe living cells. Arrays of defined cavities provide standardized geometric boundaries for individual cells or groups of cells. Imaging such cell-arrays in scanning time lapse mode yields hundreds of single cell trajectories and hence ample statistics for computational data analysis. We study single cell gene expression, cell migration and apoptotic events with precise spatio-temporal control. To this end we develop biofabrication techniques, including photo-lithography, hot-embossing, galvanic, soft lithography, 3D printing and microcontact printing, to create two-dimensional (2D) and three-dimensional (3D) pattern, cavities and channels made of biocompatible materials like PDMS, COC, hydrogels and proteins.The assays allow for long-term observation of growth and function of individual living cells, interacting groups of cells and organoids. We aim to build 3D microenvironments that control cell behavior, such as guidance of cell migration and guided interaction with nanoscale objects including cell-lipidnanoparticle interactions.
