  • Self-fueled particles for propulsion through flowing aqueous fluids
    Patent number: 12226520
    Abstract: A simple, self-propelling particle system is disclosed that can deliver a cargo through flowing aqueous solutions. This disclosure provides a non-aqueous composition comprising: (i) particles formed of a carbonate salt and having an average diameter of about 100 ?m or less; and (ii) an acid in solid form. The particles may be associated with a cargo molecule or particle. In mouse models of severe hemorrhage, the propelled particles are able to deliver a procoagulant enzyme and halt bleeding.
    Type: Grant
    Filed: March 4, 2022
    Date of Patent: February 18, 2025
    Assignees: The University of British Columbia, The General Hospital Corporation
    Inventors: Christian Kastrup, Ju Hun Yeon, James Baylis, Thomas Frederick Burke

  • Saturation analysis
    Patent number: 4030886
    Abstract: The invention provides a method and a kit for the saturation analysis of a steroid characterized by the use of a selenium-75 labelled version of the steroid to be assayed. Selenium-75 derivatives of steroids are quite simple to prepare and have practical advantages over other radioactively labelled steroids. Lists of derivatives and examples of competitive radio-assays are given.
