(a) Trajectories of superparamagnetic microparticles, suspended in 3.6% w/w dextran in PBS, flowing at 50 μl/h, at the vicinity of pure PDMS microstructures, in presence of the permanent magnets. The flow is from left to right. (b) Evolution of the deviation ΔY of the beads versus their position upstream of the microstructure Y0, for a pure PDMS microstructure with external magnetic field (solid squares) and for a i-PDMS microstructure without the permanent magnets (open circles). The beads are flowing at 50 μl/h. The curve is a guide for the eyes.
