  • Endotoxin testing assay and method of same
    Patent number: 11892397
    Abstract: A pyrogenicity test method and assay of endotoxins allows for rapid and ultrahigh sensitivity testing of parenteral pharmaceuticals or medical devices that contact blood or cerebrospinal fluid by employing a Limulus Amoebocyte Lysate (LAL) assay monitored with a photonic-crystal biosensor. The photonic-crystal biosensor is capable of determining the presence of endotoxins in a test sample by detecting shifts in the resonant condition of an open microcavity affected by the changes in the refractive index of the analyte solutions used.
    Type: Grant
    Filed: May 10, 2021
    Date of Patent: February 6, 2024
    Assignee: Board of Regents, The University of Texas System
    Inventors: Jing Yong Ye, Jonathan D. Scudder

  • Limulus amoebocyte lysate assay and method of same
    Patent number: 11099189
    Abstract: A pyrogenicity test assay and method of pyrogen testing that allows for rapid and ultrahigh sensitivity testing of parenteral pharmaceuticals or medical devices that contact blood or cerebrospinal fluid by employing a Limulus Amoebocyte Lysate (LAL) assay utilizing a photonic-crystal biosensor. The photonic-crystal biosensor is capable of determining the presence of endotoxins in a test sample by monitoring shifts in the resonant wavelength of an open microcavity affected by the changes in the refractive index of the analyte solutions used.
