    Abstract: A sample-processing device (150) comprises a unitary body (152), preferably a molded polymeric part, having formed therein a reaction chamber (154) for chemically reacting a sample, a separation region (158) for separating components of the sample, and a transition region (156) connecting the reaction chamber (154) to the separation region (158). The reaction chamber (154), transition region (156), and separation region (158) are formed in and enclosed by the unitary body (152). Additionally, the transition region (156) includes at least one flow restrictor (180) for controlling the flow of fluid between the reaction chamber (154) and the separation region (158). Further, the portion of the unitary body (152) defining the transition region (156) has lower thermal conduction than the portion of the body defining the reaction chamber (154) so that the transition region (156) thermally isolates the reaction chamber (154) from the separation region (156). In a preferred embodiment, the reaction chamber (154) is an amplification chamber for amplifying nucleic acid in the sample, and the separation region (158) comprises an electrophoresis column or capillary containing a suitable matrix material, such as electrophoresis gel or buffer, for separating nucleic acid fragments in the sample. Electrodes (167, 168, 169) are embedded in the body (152) for forcing the sample to flow from the reaction chamber (154) to the separation region (158). The unitary body (152) may also be surrounded by external, functional components such as an optical detector (186) for detecting separated components of the sample.

    Abstract: A multi-site reactor system (60) provides dynamic, independent, computer-implemented control of each reaction site, permitting different thermal profiles to be performed on samples at different reaction sites simultaneously. The system includes reaction vessels (2) for holding reaction mixtures and heat-exchanging modules (37) for receiving the vessels. The system also includes a controller (64) for independently controlling each heat-exchanging module (37) to heat and/or cool the reaction mixture contained therein. The controller (64) includes an adaptive control program for dynamically adjusting the duration or intensity of power pulses provided to each heating element and for dynamically adjusting the duration of fan operation to attain target temperatures quickly and accurately without overshooting or undershooting the target.

    Abstract: The invention presents a microfluidic device and method for separating a desired material, such as nucleic acid, from other materials in a fluid sample. In a preferred embodiment, the device comprises a microfabricated chip (20) having an inlet port (28), an outlet port (30), and an extraction chamber (26) in fluid communication with the ports. The chamber (26) has internal attachment surfaces for capturing the desired material from the fluid sample as the sample flows continuously through the chamber. The captured material may then be eluted by forcing an elution fluid to flow through the chamber (26), thus releasing the material from the internal surfaces into the elution fluid. The flow-through design of the device allows target material from a relatively large volume of fluid sample to be concentrated into a much smaller volume of elution fluid. The internal surfaces are preferably formed by an array of columns (32) integrally formed with a wall of the chamber (26) and extending into the chamber (26). The collumns (32) provide a large surface area for capturing the desired material. The device also preferably includes an integrated heater (34) for increasing elution efficiency.
