  • Patent number: 9873090
    Abstract: A method for fabricating isolated pores in an inorganic membrane includes the steps of patterning the inorganic membrane to selectively expose a portion of the membrane, forming a plurality of tracks of material damage in the exposed portion of the inorganic membrane by irradiation with energetic ions, and chemically etching the track damaged material to define the pores through the inorganic membrane with a predetermined geometrically defined cross sectional shape and with a controlled diameter range from less than 1 nanometer and up to micrometer scale.
    Type: Grant
    Filed: August 16, 2013
    Date of Patent: January 23, 2018
    Assignee: The Regents of the University of California
    Inventors: Zuzanna S. Siwy, Ivan V. Vlassiouk, Pavel Yu Apel, Sergey N. Dmitriev
  • Patent number: 9658206
    Abstract: A method for multiplex characterization of individual particles by their size, shape, mechanical properties (deformability), and chemical affinity to recognition agents. The analysis can be performed from concentrated solutions. The method detects transient sticking of particles in the pore and points to its location along a pore axis. If a pore is decorated with a recognition agent for an analyte present in a solution, it is possible to distinguish specific binding at the place of the recognition agent, and non-specific adsorption of the analyte. The method confirms whether any individual particle or hydrogel completely translocates the pore and allows unambiguous detection and characterization of multiple particles or hydrogels in the pore, which would previously corrupt the results, so that higher analyte concentrations can be used for faster analysis.

  • Patent number: 8385046
    Abstract: A capacitor device having a first conductive element and a second conductive element. The capacitor includes a porous membrane disposed between the first and second conductive elements. The capacitor has pores included in the porous membrane extending from the first conductive element to the second conductive element, and a conductive material is disposed inside the pores and in contact with the first conductive element.
