Abstract
An apparatus for mass producing monodisperse microbubbles contains a microfluidic flow focusing device. The microfluidic flow focusing device includes a dispersed phase fluid supply channel having an outlet that discharges into a flow focusing junction, a continuous phase fluid supply channel having an outlet that discharges into the flow focusing junction, and a bubble formation channel having an inlet disposed at the flow focusing junction. The configuration of the flow focusing junction is such that, in operation, a flow of dispersed phase fluid discharging from the outlet of the dispersed phase fluid supply channel is engageable in co-flow by a focusing flow of continuous phase fluid discharging from the outlet of the at least one continuous phase fluid supply channel under formation of a gradually thinning jet of dispersed phase fluid that extends into the inlet of the bubble formation channel.
