    摘要： A device for separating an analyte from a fluid sample comprises a cartridge incorporating a flow-through microfluidic chip. The microfluidic chip includes an extraction chamber having an array of microstructures for capturing the analyte and for subsequently releasing the captured analyte into an elution fluid. Each of the microstructures has an aspect ratio of at least 2:1. The cartridge also includes channels and at least one low controller (e.g., one or more valves) for directing the flow of the sample and elution fluid through the microfluidic chip. The cartridge may optionally include a lysing region for lysing sample components (e.g., cells spores, or microorganisms), a waste chamber for storing waste fluid, and reaction or detection chambers for amplifying or detecting the analyte.

    摘要： 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.
