The understanding of microparticle transport in flows and complex environments is crucial in numerous situations, ranging from the depollution of oceans to prevention of bacterial contamination in soils or medical devices, to the development of particle separation devices or even motion inside the cell nucleus. In most cases, microparticles have complex shapes and properties, as elongated or more complex forms, they can be deformable and, in some cases, self-propelled. These particles are interacting with flows in complex environments such as bifurcating networks, porous media or the crowded interieur of the cell. Particle transport then results from the interplay between particle properties, flow properties and the characteristics of the environment. Here we will investigate the transport of rigid and flexible fibers in complex flows using microfluidic model systems. We will address the question of individual particle dynamics and morphologies for polymeric fibers and actin filaments and will discuss their role in particle transport. The knowledge gained in simple flows will be used to address transport in the presence of obstacles or though pillar arrays. We will address the sorting potential of such geometries.
