Agarose capsules were prepared using a droplet breakup method in a coflowing stream. Subsieve-size capsules 76±9 μm in diameter were obtained by extruding 4 wt% agarose solution from a needle (300 μm inner diameter) at a velocity of 1.2 cm/s into an ambient liquid paraffin flow of 20.8 cm/s. Increasing the flow rate of the liquid paraffin and decreasing that of the agarose solution resulted in a decreased resultant capsule diameter. Reduction in diameter from several hundred micrometers to subsieve-size (
