    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.
