Definitions

  • Another object of the invention is to provide a multi-layered microfluidic device that includes active components such as electrodes, heating elements, or sensors.
  • channel narrowings can be implemented between two layers, as shown in FIGS. 16 and 17, or within a single layer, as shown in FIGS. 18-20, if the layer thickness and manufacturing technique permit structures to be formed in both faces of the layer.
  • the mixer circuit depicted in FIGS. 25A-25D can also be implemented in multiple thin layers. If multiple thin layers are used such that fluid circuit structures are cut through entire layer thicknesses, the "island" of material surrounded by the main channel and the side chamiel will be unsupported, which may complicate manufacturing.
  • the circuit may thus be formed in multiple layers 720-724 as shown in FIG. 26. Fluid enters at opening 725 in layer 720. Main channel 726 and side channel 727 are formed in layer 721, as is passive valve 728. Small opening 729 in layer 722 forms the passive valve just before the intersection of side channel 727 with main channel 726. The side and main channels come together at channel 731 in layer 723.
  • FIG. 3 A depicts a three-dimensional microfluidic device 300 that performs serial dilution of a sample and delivers sample solutions and a series of appropriate reagents/reactants to a diagnostic surface 303 for the performance of a multiplexed immunoassay, e.g., an Enzyme Linked Immuno-absorbent Assay or "ELISA".
  • the microfluidic circuit is designed to interface with a diagnostic surface 303 such as a slide or microtiter plate having small regions 3181-318e containing immobilized capture antibodies specific for a analyte(s) of interest.
  • the device has been simplified to more clearly illustrate its principles of operation.
