抄録

To form monodisperse water-in-oil droplets in a fully automated fashion, we fabricated a pumpless microfluidic device consisting of top and bottom polydimethylsiloxane slabs. All microstructures required for droplet formation were directly patterned on the surfaces of two polydimethylsiloxane slabs using CO2 laser micromachining, facilitating rapid fabrication of the current device. This device formed uniformly sized droplets (a coefficient of variation for droplet diameters of <4%) at a rate of ∼220 droplets/s.
