Abstract: A fluid control and processing system for controlling fluid flow among a plurality of chambers comprises a body including a fluid processing region continuously coupled fluidicly with a fluid displacement region. The fluid displacement region is depressurizable to draw fluid into the fluid displacement region and pressurizable to expel fluid from the fluid displacement region. The body includes at least one external port. The fluid processing region is fluidicly coupled with the at least one external port. The fluid displacement region is fluidicly coupled with at least one external port of the body. The body is adjustable with respect to the plurality of chambers to place the at least one external port selectively in fluidic communication with the plurality of chambers. One or more of the chambers may be a processing chamber which includes two ports configured to selectively engage the at least one external port of the body, and a fluid processing material such as an enrichment material or a depletion material. In some embodiments, one or more chambers may include a separation channel, and an electric field may be applied across the separation channel.

Abstract: A cartridge for conducting a chemical reaction includes a body having at least one flow path formed therein. The cartridge also includes a reaction vessel extending from the body for holding a reaction mixture for chemical reaction and optical detection. The vessel comprises a rigid frame defining the side walls of a reaction chamber. The frame includes at least one channel connecting the flow path to the chamber. The vessel also includes flexible films or sheets attached to opposite sides of the rigid frame to form opposing major walls of the chamber. In addition, at least two of the side walls are optically transmissive and angularly offset from each to permit real-time optical detection of analyte in the reaction chamber.

Abstract: An apparatus for disrupting cells or viruses comprises a container having a chamber for holding the cells or viruses. The container includes at least one flexible wall defining the chamber. The apparatus also includes a transducer for impacting an external surface of the flexible wall to generate pressure waves in the chamber. The apparatus also includes a pressure source for increasing the pressure in the chamber. The pressurization of the chamber ensures effective coupling between the transducer and the flexible wall. The apparatus may also include beads in the chamber for rupturing the cells or viruses.

Abstract: Embodiments of the invention provide an efficient and effective technique for storing and dispensing reagent beads. In one embodiment, an apparatus is provided for dispensing reagent beads contained in a bead storage device which includes a bead carrier having a plurality of wells; a plurality of reagent beads disposed in the wells; and a cover tape releasably attached to the bead carrier to cover the wells and retain the reagent beads in the wells. The apparatus comprises a channel in which to place the bead storage device with the bead carrier facing a support wall of the channel and the cover tape facing a stripping wall of the channel. The stripping wall includes a stripping gap disposed between a stripping edge and an opposite edge, and a dispense opening provided adjacent the opposite edge on a side of the stripping wall opposite from the stripping edge. The cover tape is insertable through the stripping gap to be pulled against the stripping edge to peel the cover tape from the bead carrier to move the wells of the bead carrier inside the channel toward the dispense opening and expose the wells individually to dispense the reagent beads.

Abstract: An analyte is separated from a fluid sample by introducing the sample into a cartridge having a sample port and a first flow path extending from the sample port. The first flow path includes an extraction chamber containing a solid support for capturing the analyte from the sample. The cartridge has a second flow path for eluting the captured analyte from the extraction chamber, the second flow diverging from the first flow path after passing through the extraction chamber. The sample is forced to flow through the extraction chamber and into a waste chamber, thereby capturing the analyte with the solid support as the sample flows through the extraction chamber. The captured analyte is then eluted from the extraction chamber by forcing an elution fluid to flow through the extraction chamber and along the second flow path.
