US Patent 11919002 Devices and methods for generating and recovering droplets

The invention provides kits, devices, methods, and systems for forming droplets or particles and methods of their use. The devices may be used to form droplets of a size suitable for utilization as microscale chemical reactors, e.g., for genetic sequencing. In general, droplets are formed in a device by flowing a first liquid through a channel and into a droplet formation region including a second liquid, i.e., the continuous phase. The invention allows for more efficient recovery of droplets or processed droplets.
