    摘要: The present invention is directed to methods of improving accuracy of droplet metering using at least one on-actuator reservoir as the fluid input. In some embodiments, the on-actuator reservoir that is used for metering droplets includes a loading port, a liquid storage zone, a droplet metering zone, and a droplet dispensing zone. The on-actuator reservoirs are designed to prevent liquid flow-back into the loading port and to prevent liquid from flooding into the droplet operations gap in the dispensing zone.

    摘要: Droplet actuators that include molecular barrier coatings are provided. The molecular barrier coating may be provided atop the conductive layer of the top substrate, atop the droplet operations electrodes of the bottom substrate, or both. Where the conductive layer of the top substrate and/or the droplet operations electrodes of the bottom substrate are formed of an electrically conductive organic polymer, such as poly(3,4-ethylenedioxythiophene) poly(styrenesulfonate) (PEDOT:PSS), the molecular barrier coating helps to immobilize the contents of the PEDOT:PSS layer. Further, the molecular barrier coating reduces, preferably entirely eliminates, moisture from seeping into the electrically conducting organic polymer. Methods of conducting droplet operations using the disclosed droplet actuators are also provided.

    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 provides a method of redistributing magnetically responsive beads in a droplet. The method may include conducting on a droplet operations surface one or more droplet operations using the droplet without removing the magnetically responsive beads from the region of the magnetic field. The droplet operations may in some cases be electrode-mediated. The droplet operations may redistribute and/or circulate the magnetically responsive beads within the droplet. In some cases, the droplet may include a sample droplet may include a target analyte. The redistributing of the magnetically responsive beads may cause target analyte to bind to the magnetically responsive beads. In some cases, the droplet may include unbound substances in a wash buffer. The redistributing of the magnetically responsive beads causes unbound substances to be freed from interstices of an aggregated set or subset of the magnetically responsive beads.
