Flow focusing microfluidics
WebJan 1, 2024 · As microfluidics only deal with fluids in movement, passive methods rely on the variation of intrinsic parameters, such as flow velocity and material properties to modify inertial, viscous, or capillary forces. On the other hand, active methods require an external stimulus as electrical, magnetic, or centrifugal forces.
