  • Magnetohydrodynamic Microfluidic Systems Including Modified Electrodes And Methods Of Using The Same
    Publication number: 20180238830
    Abstract: A magnetohydrodynamic microfluidic system and a method of pumping a fluid using a magnetohydrodynamic system are disclosed. The method includes applying at least one of an electric current and an electric voltage to a first modified electrode and a second electrode to generate an ionic current between the first modified electrode and the second electrode and to cause a current carrying species to move to or from the modified electrode, applying a magnetic field perpendicular to an ionic current vector, the magnetic field and the ionic current combining to induce flow of the fluid in a direction perpendicular to the magnetic field and the ionic current vector, and maintaining fluid flow by recharging the modified electrode.

  • Needle Biopsy Imaging System
    Publication number: 20070173718
    Abstract: Imaging techniques. Radiation is directed from a source onto a sample using an endoscope having cellular or subcellular resolution. The endoscope includes one or more fibers. The fibers have a proximate end and a distal end, and the distal end is lensless. A focal plane of the endoscope is substantially at a tip of the distal end. Radiation from the sample is directed onto a detector to diagnose or monitor the sample.
