    摘要: In a microfluidic system using electrokinetic forces, the present invention uses electrical current or electrical parameters, other than voltage, to control the movement of fluids through the channels of the system. Time-multiplexed power supplies also provide further control over fluid movement by varying the voltage on an electrode connected to a fluid reservoir of the microfluidic system, by varying the duty cycle during which the voltage is applied to the electrode, or by a combination of both. A time-multiplexed power supply can also be connected to more than one electrode for a savings in cost.

    摘要: The invention provides improved systems, devices, and methods for analyzing a large number of sample compounds contained in standard multiwell microtiter plates or other array structures. The multiwell plates travel along a conveyor system to a test station having a microfluidic device. At the test station, each plate is removed from the conveyor and the wells of the multiwell plate are sequentially aligned with an input port of the microfluidic device. After at least a portion of each sample has been input into the microfluidic channel system, the plate is returned to the conveyor system. Pre and/or post testing stations may be disposed along the conveyor system, and the use of an X-Y-Z robotic arm and novel plate support bracket allows each of the samples in the wells to be input into the microfluidic network through a probe affixed to a microfluidic chip. A clamshell structure having a hinged lid can releasably support the chip while providing and/or accommodating the electrical, optical, structural, and other interface connections between the microfluidic device and the surrounding system.
