摘要: A cartridge for separating a desired analyte from a fluid sample has a sample flow path and a lysing chamber in the sample flow path. The lysing chamber contains at least one filter for capturing cells or viruses from the sample as the sample flows through the lysing chamber. Beads are also disposed in the lysing chamber for rupturing the cells or viruses to release the analyte therefrom. An analyte flow path extends from the lysing chamber and diverges from the sample flow path. The analyte flow path preferably leads to a reaction chamber for chemically reacting and optically detecting the analyte. The cartridge also includes at least one flow controller (e.g., valves) for directing the sample into the waste chamber after the sample flows through the lysing chamber and for directing the analyte separated from the sample into the analyte flow path.

摘要: A method for extracting nucleic acid from a fluid sample comprises the steps of introducing the sample into a cartridge having a sample flow path and a lysing chamber in the sample flow path. The lysing chamber contains at least one filter for separating cells or viruses from the sample. The sample is forced to flow through the lysing chamber to capture the cells or viruses with the filter, while used sample fluid flows to waste. The captured cells or viruses are disrupted to release their nucleic acid, the nucleic acid is eluted from the lysing chamber, and optionally the nucleic acid is amplified and detected in a reaction chamber of the cartridge.

摘要: This invention comprises an apparatus and method for the manipulation of materials, including particles, cells, macromolecules, such as proteins, nucleic acids and other moieties, in fluid samples. The apparatus comprises an enclosed chamber on a chip having an internal microstructure with surface area substantially greater than the facial surface area of the internal structure. Generally the internal microstructure comprises a continuous network of channels, each of which has a depth substantially greater than its width. The network may comprise a single channel, a single channel with multiple branches, multiple channels, multiple channels with multiple branches, and any combination thereof. The internal structure may present an inert, non-reactive surface, or be coated with a reactive ligand, or be electrically conductive and optionally be coated with an electrical insulator. Discrete portions of the internal structure may differ in structural and surface properties. Multiple chips may be linked together to create a multiplexed array of chambers, optionally linked to other analytical devices.

摘要: A system for controlling the temperature of a reaction mixture comprises at least one heating device for heating the mixture and a power regulator for regulating the amount of power supplied to the heating device. A controller in communication with the power regulator includes program instructions for heating the reaction mixture by setting a variable target temperature that initially exceeds a desired setpoint temperature for the mixture. When the heating device reaches a threshold temperature, the variable target temperature is decreased to the desired setpoint temperature. In another embodiment, the controller includes an adaptive control program for dynamically adjusting the duration or intensity of power pulses provided to the heating device.

摘要: An analysis device comprises a body having a reaction chamber for chemically reacting a sample, a separation region for separating components of the sample, and a transition region connecting the reaction chamber to the separation region. The transition region includes at least one valve for controlling the flow of fluid between the reaction chamber and the separation region. Further, the transition region thermally isolates the reaction chamber from the separation region. In a preferred embodiment, the reaction chamber is an amplification chamber for amplifying nucleic acid in the sample, and the separation region comprises an electrophoresis channel containing a suitable matrix material, such as electrophoresis gel or buffer, for separating nucleic acid fragments. Electrodes are embedded in the body for separation of sample components. The body may also be surrounded by external, functional components such as an optical detector for detecting separated components of the sample.
