Abstract:
Methods involve forming a droplet, and contacting the droplet with a fluid stream, wherein a portion of the fluid stream integrates with the droplet to form a mixed droplet. Methods for merging two liquid phases in which only one phase is in the form of a droplet at least at the point of merging A second phase is injected into the drops directly from a continuous stream. Methods of the invention provide a simple and reliable approach to sample fluid mixing because only one of the two phases is dispersed as a droplet prior to its merge with the other phase.
Abstract:
Methods of performing sandwich assays in droplets are disclosed. Further disclosed are methods for detecting a target analyte that involve forming a compartmentalized portion of fluid including a portion of a sample suspected of containing a target analyte and a sample identifier, a first binding agent having a target identifier, and a second binding agent specific to the target analyte under conditions that produce a complex of the first and second binding agents with the target analyte; separating the complexes, and detecting the complexes, thereby detecting the target analyte.
Abstract:
The present invention generally relates to systems and methods to create stable emulsions with low rates of exchange of molecules between microdroplets.

The invention generally relates to methods for forming mixed droplets. In certain embodiments, methods of the invention involve forming a droplet, and contacting the droplet with a fluid stream, wherein a portion of the fluid stream integrates with the droplet to form a mixed droplet.
Abstract:
The invention generally relates to methods for quantifying an amount of enzyme molecules. Systems and methods of the invention are provided for measuring an amount of target by forming a plurality of fluid partitions, a subset of which include the target, performing an enzyme-catalyzed reaction in the subset, and detecting the number of partitions in the subset. The amount of target can be determined based on the detected number.

Abstract:
The present invention provides thermocycling devices useful for amplification of nucleic acids in droplets. The thermocycling device utilizes the flow of one or more fluids through a main compartment at temperatures sufficient to conduct a polymerase chain reaction. Methods of amplifying nucleic acids in droplets are also provided.
Abstract:
The invention provides barcode libraries and methods of making and using them including obtaining a plurality of nucleic acid constructs in which each construct comprises a unique N-mer and a functional N-mer and segregating the constructs into a fluid compartments such that each compartment contains one or more copies of a unique construct. The invention further provides methods for digital PCR and for use of barcode libraries in digital PCR.
