  • Preparation of sub 100 A magnetic particles and magnetic molecular switches
    Patent number: 5935866
    Abstract: Inorganic oxides of substantially uniform particle size distribution are prepared by contacting aqueous solutions of an inorganic salt and an inorganic base across a porous membrane wherein the membrane contains a plurality of pores which allows for precipitation of a substantially mono-disbursed size inorganic oxide particles on one side of the membrane and precipitation of a salt of the corresponding base on a second side of the membrane.
    Type: Grant
    Filed: June 8, 1992
    Date of Patent: August 10, 1999
    Assignee: Binax NH, Inc.
    Inventors: Mark S. Chagnon, John R. Ferris, Michelle J. Carter, Tracy J. Hamilton, Maria A. Gray
  • Preparation and use of novel injectable RES avoiding inorganic particles for medical application
    Patent number: 5547682
    Abstract: Novel N-RES agents for use in vitro and in vivo medical and biological applications, such as, for example MRI and/or intravenous administration of pharmaceutical agents are described. The novel N-RES agents are prepared by coating inorganic core particles with a poly(acrylic acid)--poly(alkylene ether) graft copolymer. The resulting polymer-coated inorganic particle cores are useful as imaging agents, therapeutic agents or carriers having increased circulation time due to decrease uptake or recognition by the RES.

    Date of Patent: August 20, 1996
    Assignee: BioQuest, Incorporated
    Inventors: Mark S. Chagnon, Stephen E. Burkle, Michelle J. Carter, Tracy J. Hamilton, John Havelick, Jr., Deborah A. Kaplan, Kristin L. Marzloff
  • Solid care therapeutic compositions and methods for making same
    Patent number: 5389377
    Abstract: A liposome composition which comprises a substantially uniform sized inorganic core coated with an amphipathic organic compound and further coated with a second amphipathic vesicle forming lipid. Also disclosed are novel phenyl lipid compounds which serve as the amphipathic vesicle forming lipid and methods are described for delivering a drug for slow release into the blood stream, and for targeting a selected tissue or cells with the inorganic core liposome compositions.
    Type: Grant
    Filed: October 7, 1992
    Date of Patent: February 14, 1995
    Assignee: Molecular Bioquest, Inc.
    Inventors: Mark S. Chagnon, John R. Ferris, Tracy J. Hamilton, Edwin A. Rudd, Michelle J. Carter
  • Biodegradable magnetic microclusters and methods for making them
    Patent number: 5382468
    Abstract: Subdomain metal or metal oxide particles covalently coupled to chemically reactive organic moieties and subsequently reacted together to form biodegradable magnetic microclusters are disclosed. The magnetic microcluster can be used as contrast agents in NMR imaging for the production of images suitable for use in diagnosis, for in vivo delivery and targeting of drugs, as in vivo, biodegradable agents for the sequestering of free metal ions in the treatment of metal driven disease.
