    Abstract: The presence of a detectable entity within a detection volume of a microfabricated elastomeric structure is sensed through a change in the electrical or magnetic environment of the detection volume. In embodiments utilizing electronic detection, an electric field is applied to the detection volume and a change in impedance, current, or combined impedance and current due to the presence of the detectable entity is measured. In embodiments utilizing magnetic detection, the magnetic properties of a magnetized detected entity alter the magnetic field of the detection volume. This changed magnetic field induces a current which can reveal the detectable entity. The change in resistance of a magnetoresistive element may also reveal the passage of a magnetized detectable entity.

One or more well regions are formed in a first portion of the deformable fluid layer and are capable of holding a fluid therein. The one or more channel regions are formed in a second portion of the deformable fluid layer and are coupled to one or more of the well regions. An active region is formed in the deformable fluid layer.

    Abstract: An injection molding method of fabricating a carrier for holding a microfluidic device can form all of the desired features of such a carrier, including wells, channels and ports having smaller dimensions and greater density than previously achieved, while reducing or avoiding fracturing and the need for drilling the substrate to form certain features, in particular the ports. The carrier includes a substrate with a plurality of wells, each well defining a volume of between 0.1 μl and 100 μl; a plurality of channels within the substrate wherein each well is in fluid communication with at least one of the plurality of channels; a plurality of ports within the carrier substrate wherein each port is for coupling with regions in the carrier substrate adapted to receive fluids or pressure; and a receiving portion for receiving a microfluidic device and placing the microfluidic device in fluid communication with the plurality of wells. The carrier has a polymeric composition and/or an array of structural features achieved via the injection molding fabrication technique that enhance its performance and compatibility with existing instrumentation.
