MECHANOBIOLOGY PLATFORM

MECHANOBIOLOGY PLATFORMS

Health, diagnostic, therapeutic tools

Our mechanobiology 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.


TOOLS AND EQUIPMENT

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 3D microprocessing: 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).



METHODOLOGY

Design of a simplified system

and experimentation under controlled conditions
