Microfluidic device used to generate and extract microparticles. (a) A schematic illustration of the microfluidic device. (b) Criterion for maintaining a stable interface between carrier oil emulsion and aqueous extracting solution. Open and solid squares represent unstable and stable interfaces, respectively. The dashed line represents the criterion of μV = 6 × 10−4 N/m for stable interface.
