  • Methods for radiolabeling synthetic polymers
    Patent number: 9381262
    Abstract: The present invention relates to a method for preparing a radiolabeled synthetic polymer, the method comprising contacting a synthetic polymer with a carbon encapsulated nanoparticle composite having a radioactive particulate core in an aqueous medium comprising an electrolyte concentration or pH selected to promote short-range attractive forces between the nanoparticles and the synthetic polymer by attenuating long-range electrostatic repulsive forces.
    Type: Grant
    Filed: April 23, 2009
    Date of Patent: July 5, 2016
    Assignee: The Australian National University
    Inventors: Ross Wentworth Stephens, Timothy John Senden, David Wallace King
  • Methods for radiolabeling macromolecules
    Patent number: 9283291
    Abstract: The present invention relates to a method for preparing a radiolabeled macromolecule, the method comprising contacting a macromolecule with a carbon encapsulated nanoparticle composite having a radioactive particulate core in an aqueous medium comprising a pH selected to promote short-range attractive forces between the nanoparticles and the macromolecule by attenuating repulsive electrostatic forces.
