  • Publication number: 20190154715
    Abstract: A continuous throughput microfluidic system includes an input system configured to provide a sequential stream of sample plugs; a droplet generator arranged in fluid connection with the input system to receive the sequential stream of sample plugs and configured to provide an output stream of droplets; a droplet treatment system arranged in fluid connection with the droplet generator to receive the output stream of droplets in a sequential order and configured to provide a stream of treated droplets in the sequential order; a detection system arranged to obtain detection signals from the treated droplets in the sequential order; a control system configured to communicate with the input system, the droplet generator, and the droplet treatment system; and a data processing and storage system configured to communicate with the control system and the detection system.
