Cells - Biophysics - Growth - Adhesion - Morphology - Mechanics - Fluxes
Our Biomechanics platform is dedicated to the study of mechanical interactions within biological systems, from the cell scale to the tissue. Our research focuses on biophysical phenomena such as cell adhesion, migration, growth and morphology, and the interactions with fluid dynamics.
▪ therapeutic tools
The platform regroups high performance tools for the characterisation of the mechanical properties of cell and tissue, for bio-rheology studies, and imaging.
▪ Imaging tools (confocal and atomic force microscopy): 3D study of cellular or tissue structures, imaging of moving objects, cell or tissue topology analysis
▪ Tools for the micro-scale characterisation of adhesion orvisco-elastic forces (AFM)
2D and 3Dmicroprocessing: design of microfluidic circuits, micro-structured substrates
▪ Environmental chambers: preparation of standardized biological material
▪ Microrheology tools and techniques: study of the reological properties of complex fluids (biological fluids with low stability in vitro, vesicles or microorganisms suspensions).
