    摘要: In one aspect, the present invention provides methods, devices, and systems for ensuring that multiple components of a mixture are fully mixed in a continuous flow microfluidic system while ensuring that mixing between segments flowing through the chip is minimized. In some embodiments, the present invention includes mixing fluids in a droplet maintained at the tip of a pipette before the mixture is introduced to the microfluidic device. In another aspect, the present invention provides a pipette tip having a ratio of an outside diameter to an inside diameter that provides sufficient surface area for a droplet comprising up to the entire volume of the liquid to suspend from the pipette tip intact. In yet another aspect, the present invention provides methods, devices, and systems for delivering a reaction mixture to a microfluidic chip comprising a docking receptacle, an access tube and a reservoir.

    摘要: A method and device for digital multiplex PCR assays employ a microfluidic chip for performing real-time, continuous flow PCR within microchannels of the chip. A stream of sample material is introduced into each microchannel and alternating boluses of assay-specific reagents and buffer are introduced into the stream to form sequentially configured test boluses. A PCR procedure is performed on the test boluses followed by a thermal melt procedure. During the thermal melt procedure, fluorescent output is detected and fluorescence vs temperature data is collected and compared to expected normal correlations. The results, positive or negative, are converted to digital format, with positive results designated as “1” and negative results designated as “0”, or vice versa.
