  • Electrical detection using confined fluids
    Patent number: 9110010
    Abstract: A device having: a laminar flow channel for liquids; two or more electrodes; a confining fluid inlet; a sample inlet; and a meter for measuring the impedance of any fluid between the electrodes. The device may have one or more specific binding sites, or it may have sheathing and unsheathing fluid transporting structures. A method of: providing the device; flowing a confining fluid and a conductive liquid that may contain cells or particles through the channel as described herein; and measuring the impedance between the electrodes.
    Type: Grant

  • Method and apparatus for measuring changes in cell volume
    Publication number: 20050239046
    Abstract: A method and apparatus for measuring changes in cell volume generally includes introducing cells into a chamber having a volume between 2 and 100 times the volume of the introduced cell. A first electrically conductive extracellular fluid is introduced into the chamber and a current is applied. The current flow is measured. The first fluid is exchanged with a second electrically conductive extracellular fluid and a current is applied. The current flow is measured. The first current flow result and the second current flow result are used in conjunction with known current flows to monitor changes in the volume corresponding to fluid flow between the cell and an extracellular fluid.
