Patchy colloids are particles with a solid core and a discrete number of interaction sites. In this seminar I will present simulation and theoretical results of a model binary mixture of patchy colloids under gravity. By tuning the buoyant masses of the colloids we can control the sequence of fluid stacks formed in sedimentation-diffusion-equilibrium. We find complex stacking sequences with up to four layers and reentrant network formation.
