  • Surface modification for improving biocompatibility
    Patent number: 7589070
    Abstract: A therapeutic delivery system efficiently introduces biologically active molecules to mammalian cells without the use of synthetic polymers or biopolymer coatings. Surface modification of a metal support, such as a medical device, results in a single molecular layer that can fasten various molecules, thereby minimizing any cellular inflammatory response while enhancing biocompatibility.
    Type: Grant
    Filed: June 14, 2002
    Date of Patent: September 15, 2009
    Assignee: The Children's Hospital of Philadelphia
    Inventors: Robert J. Levy, Ivan Alferiev, Cunxian Song, Ilia Fishbein

  • DNA-antibody complexes to enhance gene transfer
    Publication number: 20030003100
    Abstract: Transfection efficiency can be enhanced when a complex comprising a nucleic acid, an antibody that specifically binds the nucleic acid and a cationic macromolecule is introduced into mammalian cells. Delivery of nucleic acid into these cells enables transfection at levels comparable to conventional viral delivery.
