To stick or not to stick... that is the question.
Patrick Tabeling's group in collaboration with his former post-doc, Cesare Cejas, has recently published an article underlying the mechanisms required for particles to adhere (or not adhere) onto surface walls when traveling inside a micro channel. The physics is particularly rich and the paper, using microfluidics experiments, numerical simulations, and theory demonstrates the various factors at play controlling particle trajectories: hydrodynamic forces, adhesion (van der W
