title: Pressure-driven spatiotemporal control of the laminar flow interface in a microfluidic network.
abstract: We describe a system for dynamically adjusting the position of the laminar interface between two fluids flowing inside a microfluidic channel, with a time response of less than 0.1 s, through feedback control of the channel inlet pressure.
