    Abstract: Introducing a sample solution that includes a target nucleic acid polymer into a microfluidic device that has a sample region with: (i) a flow channel in fluid communication with one fluid inlet and one fluid outlet; and (ii) a plurality of valves that, when closed, partition the flow channel into isolated reaction sites. Each valve is formed from an elastomeric membrane that separates a control channel from the flow channel and which is disposed to be deflected into or retracted out from the flow channel in response to an actuation force to the control channel, thereby forming the valve. The method includes closing the valves, thereby partitioning the flow channel into isolated reaction sites containing portions of said sample solution; exposing the reaction sites to conditions under which the nucleic acid polymer is amplified to produce an amplification product; and opening said valves and displacing sample solution out of the flow channel.

    Abstract: A microfluidic device, with elastomeric components, and having a flow channel, wherein said flow channel has a plurality of blind flow channels opening into and in fluid communication with the flow channel, each blind flow channel having an aperture portion, a channel portion and a terminus portion, and wherein a region at the terminus of each blind flow channel defines a reaction site. Each blind flow channel is associated with a valve that when closed isolates the reaction site from the flow channel. The valves associated with each of the plurality of blind flow channels in fluid communication with the flow channel are under the control of a common control channel and are coordinately closed or opened.
