High-speed on demand microfluidic droplet generation and manipulation

摘要

Methods and devices for the formation and/or merging of droplets in microfluidic systems are provided. In certain embodiments a microfluidic droplet merger component is provided that comprises a central channel comprising a plurality of elements disposed and spaced to create a plurality of lateral passages that drain a carrier fluid out of a fluid stream comprising droplets of a first fluid contained in the carrier fluid; and a deformable lateral membrane valve disposed to control the width of said center channel.
