From the separation of products on industrial filters to the propagation of pollutants in soils or the transmission of micro-organisms in biological tissues, the transport of particles through porous matrices is ubiquitous. Particle-matrix interactions involve crucial deposition mechanisms, often studied by numerical simulations, global measurements or reduced (1D or 2D) systems. By making adapted 3D porous media (transparent random packings of spheres), and taking advantage of original internal observations (MRI, confocal microscopy), we have been able to directly visualize and analyze the whole range of transport and deposition dynamics at the global and local scales. Varying in turns the particles size (tens of nanometers to tens of micr...
