  • Liposomal compositions with light illumination-induced drug release
    Patent number: 11154619
    Abstract: Provided herein is a small molecule delivery system with illumination-induced small molecule release based on the binary combination of charged liposomes containing small molecules and oppositely charged conjugates of a peptide with a photosensitizer attached to one end of peptide chain, providing binding to liposomes and their permeabilization upon light illumination.
    Type: Grant
    Filed: February 20, 2018
    Date of Patent: October 26, 2021
    Assignee: Creighton University
    Inventors: Igor Meerovich, Alekha Dash, Michael Nichols, David Smith
  • Diffusion cells and related methods
    Patent number: 10613011
    Abstract: A method of performing a diffusion test includes clamping a membrane to a body such that a first surface of the membrane is in fluid communication with an interior chamber of the body and a second surface of the membrane is exposed to ambient air, flowing a substance through the ambient air such that at least a portion of the substance lands on the second surface while the membrane is vertically oriented, and determining a concentration of the substance in the interior chamber after some of the substance has diffused through the membrane.
    Type: Grant
