    摘要： The invention is directed to a droplet actuator device and methods for integrating gel electrophoresis analysis with pre or post-analytical sample handling as well as other molecular analysis processes. Using digital microfluidics technology, the droplet actuator device and methods of the invention provide the ability to perform gel electrophoresis and liquid handling operations on a single integrated device. The integrated liquid handling operations may be used to prepare and deliver samples to the electrophoresis gel, capture and subsequently process products of the electrophoresis gel or perform additional assays on the same sample materials which are analyzed by gel electrophoresis. In one embodiment, one or more molecular assays, such as nucleic acid (e.g., DNA) quantification by real-time PCR, and one or more sample processing operations such as sample dilution is performed on a droplet actuator integrated with an electrophoresis gel. In one embodiment, an electrophoresis gel may be integrated on the top substrate of the droplet actuator.

    摘要： The invention relates to certain novel approaches to reducing or eliminating the movement of contaminants from one droplet to another on a droplet actuator via liquid filler fluid. In one application, a method of detecting an analyte is provided and includes providing in a detection window a droplet including a signal-producing substance indicative of the presence and/or quantity of an analyte and one or more magnetically responsive beads which may interfere with signal produced by the signal producing substance. The method further includes using a magnetic field for magnetically removing the magnetically responsive beads from the detection window and/or magnetically restricting the magnetically responsive beads from entering the detection window while transporting and/or retaining the droplet in the detection window. The method additionally includes detecting a signal produced by the signal-producing substance.
