Abstract

Gas encapsulant, about 1.4 nl volume, generation was performed by using a simple gas-organic-water multiphase junction. Polystyrene microcapsules containing gas of 140 μm in diameter were generated 40 capsules/sec averagely. Long time gas sealing was realized with polystyrene film of about 100 nm in thickness. Also, the droplets' size and gas amount could be controlled by flow rate control.
