摘要:
A device for performing polymerase chain reactions using cooling members not used in conventional thermal cyclers. A device for performing polymerase chain reactions may include a sample holder configured to receive a nucleic acid sample, a heating system configured to raise the temperature of the sample, a cooling system configured to lower the temperature of the sample, and a controller configured to operably control the heating system and the cooling system to cycle the device through a desired time-temperature profile. The cooling system may comprise at least one cooling member selected from a synthetic jet ejector array, a vibration-induced droplet atomization system, a vibrating diaphragm system, a piezo fan, a Cold Gun, a microchannel cooling loop, and a Cool Chip.

An apparatus for detecting labeled beads is provided. The apparatus can include: one or more irradiation sources disposed for irradiating the one or more detection zones with radiation; at least one detector disposed for collecting charges corresponding to light signals emitted from labeled beads in the one or more detection zones, which have been excited by the radiation; and a system coupled to the at least one detector for effecting time delay integration of the charges by accumulating the charges before reading the charges at the output of the at least one detector.
摘要:
Various embodiments described in the application relate to an apparatus, system, and method for fluidically controlling, within a conduit, discrete volumes of one or more fluids that are immiscible with a second fluid. The discrete volumes can be used for biochemical or molecular biology procedures involving small volumes, for example, microliter-sized volumes, nanoliter-sized volumes, or smaller. The system can comprise combinations of detectors, controllers, valves, and fluid supply units to control the spatial size, location and/or fluidic composition of discrete volumes separated from one another by a fluid that is immiscible with the fluid(s) of the discrete volumes, for example, aqueous immiscible-fluid-discrete volumes separated by an oil.
