Droplet control for microfluidics

Nanoliter droplets of uniform size
spontaneously form in microchannels
when two immiscible fluid
streams merge. This
nonlinear process involves basic physics, with the local geometry and surface
chemistry of the microchannel strongly
affecting the competition between viscous
forces tending to draw the fluids along the
channel and capillary forces tending to
form droplets so as to minimize the total
interface between the two fluids.
