Microfluid Ladders

This is an example of flipping the leading/lagging order of dyed aqueous droplets in two parallel microfluidic channels. Microfluidic ladder networks such as this one can be used to expand, contract, and even remove the space and time gap between droplets moving in parallel channels.
