Title: METHODS FOR RADIOLABELLING SYNTHETIC POLYMERS
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.
