Controlling droplet incubation using close-packed plug flow

Biomicrofluidics. 2011 Apr 4;5(2):24101. doi: 10.1063/1.3576934.


Controlling droplet incubation is critical for droplet-based microfluidic applications; however, current techniques are either of limited precision or place strict limits on the incubation times that can be achieved. Here, we present a simple technique to control incubation time by exploiting close-packed plug flow. In contrast to other techniques, this technique is applicable to very short and very long incubation times.
