  • Publication number: 20140212575
    Abstract: The present invention includes a novel self-assembling nanocomposite structure comprising a shape-persistent three-dimensional cage molecule. In one aspect, binding of nanoparticles to metal coordinating groups in the cage molecule allows for the self-assembly of the nanoparticles into a nanocomposite material. The present invention further includes methods of preparing such self-assembling nanocomposite structures.

  • Patent number: 8323632
    Abstract: The invention provides a multi-arm block copolymer for use in delivering a variety of bioactive agents. The copolymer of the invention contains a central core from which extend multiple (3 or more) copolymer arms. Each copolymer arm possesses an inner polypeptide segment and an outer hydrophilic polymer segment. Thus, the overall structure of the copolymer comprises an inner core region that includes the central core and the inner polypeptide segment, while the outer core region is hydrophilic in nature. The multi-arm copolymer of the invention is particularly useful for delivery of biologically active agents that can be entrapped within the inner core region.
