On the halt of spontaneous capillary flows in diverging open channels

Capillary microsystems are increasingly used in many different scientific domains, from biotechnology to biology and medicine, chemistry, thermics, energy and space. In such systems the energy source that is responsible for the flow is the surface energy of the walls. No external, bulky energy sources and no moving off-chip parts are needed, which make such systems compact and easily portable. This is the case of “point-of-care” or “personal self testing” systems in biotechnology and medicine, which enable patients to easily monitor in their home or at the doctor's office their physical condition and adjust their treatment without having to go to an analysis laboratory [1–4].
