Abstract

A method for generating monodisperse gaseous bubbles in a microfluidic flow-focusing device was presented. The method could generate bubbles in the range of diameters from 10 to 1000 μm. The volume of the bubbles, in the method, was found to scale with the flow rate and the viscosity of the liquid, and the pressure of the gas stream. The method was demonstrated to allow simultaneous, independent control of the size of the individual bubbles and volume fraction of the dispersed phase.
