| Popis: | Capillary microfluidics or capillarics is gaining importance in the biotechnological domain. It combines the advantages of capillary actuation that does not require pumps or syringes to move the fluids, with low-cost fabrication, user-friendliness, portability and telemedicine compatibility. In this work, we present expressions of the spontaneous capillary flow velocity in different geometrical configurations. It is shown that relatively large velocities - at the scale of microsystems — can be reached by capillary microflows. Consequently transport distances can be important. |
