Abstract: Methods of partition-based analysis. In an exemplary method, a device having a port fluidically connected to a chamber may be selected. A sample-containing fluid may be placed into the port. The sample-containing fluid may be moved from the port to the chamber. Partitions of the sample-containing fluid may be formed. A monolayer of the partitions in the chamber may be created. At least a portion of the monolayer may be imaged.

Abstract: Method of analysis. In the method, a first emulsion and a second emulsion substantially separated from one another by a spacer fluid may be formed. The first emulsion, the spacer fluid, and the second emulsion may be flowed in a channel from a fluid inlet to a fluid outlet of a heating and cooling station having two or more temperature-controlled zones, such that each emulsion is thermally cycled to promote amplification of a nucleic acid target in droplets of the emulsion. Amplification data may be collected from individual droplets of each emulsion downstream of the heating and cooling station. A level of the nucleic acid target present in each emulsion may be determined based on the amplification data collected from the individual droplets of the emulsion.

Abstract: Method of performing a droplet-based assay. The method may include obtaining droplets encapsulated by an immiscible liquid and packed closely together in a monolayer, performing a reaction in the droplets while packed closely together in the monolayer; and collecting data related to an analyte from a plurality of the droplets while the droplets remain closely packed together in the monolayer.

Abstract: The present disclosure provides methods, devices, systems and compositions for detecting nucleic acids in polymerase chain reaction assays, such as droplet digital polymerase chain reaction (ddPCR) assays. The present disclosure provides methods, devices, systems and compositions for detecting nucleic acids in ddPCR assays using intercalating dyes. A dual surfactant system with at least one fluorosurfactant and at least one non-ionic non-fluorosurfactant may be employed for droplet generation and nucleic acid detection.

Abstract: System, including methods and compositions, for making and using emulsions that include a silicone oil and a silicone surfactant. The emulsions may include aqueous droplets disposed in a continuous phase that includes a silicone oil and a silicone surfactant. The aqueous droplets may contain an analyte, optionally at partial occupancy, and/or a luminescent (e.g., photoluminescent) reporter. An assay of the analyte may be performed with the droplets. In some cases, signals may be detected from the droplets, and a characteristic of the analyte, such as an analyte level or activity, may be determined based on the signals.

Abstract: System, including methods, apparatus, and kits, for forming and concentrating emulsions. An exemplary system may comprise a device including a sample well configured to receive sample-containing fluid, a continuous-phase well configured to receive continuous-phase fluid, a droplet well, and a channel network interconnecting the wells. The system also may comprise an instrument configured to operatively receive the device and to create (i) a first pressure differential to produce an emulsion collected in the droplet well and (ii) a second pressure differential to decrease a volume fraction of continuous-phase fluid in the emulsion, after the emulsion has been collected in the droplet well, by selectively driving continuous-phase fluid, relative to sample-containing droplets, from the droplet well.

Abstract: Method of analysis. In the method, a microfluidic device defining a flow path extending from an inlet to an outlet may be selected. A sample-containing fluid may be introduced into the flow path via the inlet. Volumes of the sample-containing fluid may be isolated from one another on the flow path. A two-dimensional monolayer of the volumes may be imaged. The two-dimensional monolayer may be formed along the flow path between the inlet and the outlet.
