Abstract: The invention provides methods of conducting a nucleic acid reaction, including methods for performing digital PCR using a “droplet-in-oil” technology. In the methods, the starting sampled is segmented at least partially into a set of sample droplets each containing on average about one or fewer copies of a target nucleic acid. The droplets are passed in a continuous flow of immiscible carrier fluid through a channel that passes through a thermal cycler, whereby the target is amplified. In one implementation, the droplets are about 350 nl each and the number of positively amplified droplets is counted at the near-saturation point.

Abstract: A microfluidic analysis system (1) performs polymerase chain reaction (PCR) analysis on a bio sample. In a centrifuge (6) the sample is separated into DNA and RNA constituents. The vortex is created by opposing flow of a silicon oil primary carrier fluid effecting circulation by viscous drag. The bio sample exits the centrifuge enveloped in the primary carrier fluid. This is pumped by a flow controller (7) to a thermal stage (9). The thermal stage (9) has a number of microfluidic devices (70) each having thermal zones (71, 72, 73) in which the bio sample is heated or cooled by heat conduction to/from a thermal carrier fluid and the primary carrier fluid. Thus, the carrier fluids envelope the sample, control its flowrate, and control its temperature without need for moving parts at the micro scale.

Abstract: A multi-port liquid bridge (1) adds aqueous phase droplets (10) in an enveloping oil phase carrier liquid (11) to a draft channel (4, 6). A chamber (3) links four ports, and it is permanently full of oil (11) when in use. Oil phase is fed in a draft flow from an inlet port (4) and exits through a draft exit port (6) and a compensating flow port (7). The oil carrier and the sample droplets (3) ('aqueous phase') flow through the inlet port (5) with an equivalent fluid flow subtracted through the compensating port (7). The ports of the bridge (1) are formed by the ends of capillaries held in position in plastics housings. The phases are density matched to create an environment where gravitational forces are negligible. This results in droplets (10) adopting spherical forms when suspended from capillary tube tips. Furthermore, the equality of mass flow is equal to the equality of volume flow. The phase of the inlet flow (from the droplet inlet port (5) and the draft inlet port (4) is used to determine the outlet port (6) flow phase.
