  • Patent number: 11193914
    Abstract: A photoacoustic photon meter includes: a photoacoustic generative array including carbon nanotubes disposed in a photoacoustic generating pattern, such that the carbon nanotubes: receive photons comprising optical energy, and produce thermal energy from the optical energy; and a superstratum including a thermally expandable elastomer on which the photoacoustic generative array is fixedly disposed in position on the superstratum to spatially conserve the photoacoustic generating pattern, and such that the superstratum: is optically transparent to the photons; receives the thermal energy from the photoacoustic generative array; expands and contracts in response to receipt of the thermal energy; and produces photoacoustic pressure waves in response to the expansion and contraction, the photoacoustic pressure waves including a photoacoustic intensity and photoacoustic frequency that are based upon an amount of optical pressure applied to the carbon nanotubes by the photons, a spatial photon fluence of the photons
    Type: Grant
    Filed: January 28, 2020
    Date of Patent: December 7, 2021
    Assignee: GOVERNMENT OF THE UNITED STATES OF AMERICA, AS REPRESENTED BY THE SECRETARY OF COMMERCE
    Inventors: Jeeseong Hwang, Christopher Yung, Kimberly Ann Briggman, John Henry Lehman

  • Publication number: 20110086338
    Abstract: The invention is related to a non-biotinylated bacteriophage that comprises a nucleic acid sequence encoding a biotinylation domain, a complex that comprises a biotinylated bacteriophage and a biotin-specific ligand conjugated bioconjugate, and a method of detecting a bacterial cell in a sample comprising contacting the sample with a non-biotinylated bacteriophage that comprises a nucleic acid sequence encoding a biotinylation domain, wherein the bacteriophage is specific to the bacterial cell.
