  • Flow control in microfluidics devices by controlled bubble formation
    Patent number: 5992820
    Abstract: Provided is a fluid control device comprising: (a) a channel of capillary dimensions for conveying a liquid, (b) a bubble-forming device for forming a channel-blocking bubble in the channel, wherein such a bubble formed in the channel impedes the flow of the liquid through the channel.
    Type: Grant

  • Indirect electrode-based pumps
    Patent number: 5961800
    Abstract: Provided is an electrode-based pump having source of a pumped fluid, a conduit channel of capillary dimensions connected via a first end to the pumped fluid source and having an outlet at a second end, a piston channel with a first end that intersects the conduit channel, wherein the piston channel allows for periodic inward and outward movement of a piston plug of liquid, two or more electrodes inserted into the piston channel which define an electrode-based pump, wherein the electrode-based pump can be operated to move the piston plug of liquid inward and outward.

  • Dry elements, test devices, test kits and methods for chemiluminescent detection of analytes using peroxidase-labeled reagents
    Patent number: 5736335
    Abstract: A dry, removable analytical element can be used to detect chemiluminescent signals produced from the reaction of peroxidase and a chemiluminescent detection system. The analytical element contains at least two layers, the outer layer being non-tacky and water-soluble or water-permeable, and used to contact a gel plate or transblotting membrane in which multiple analytes are located. The resulting signal can be recorded using a photosensitive element. Test kits include the various packaged components needed to use the analytical element for analyte detection. Within the element are critical amounts of oxidase and an oxidase substrate for highly sensitive analyte detection.
