  • Ultrathin polymer film using cucurbituril derivative and method of forming the same
    Patent number: 7781050
    Abstract: Provided are an ultrathin polymer film formed by homopolymerization or copolymerization of a cucurbituril derivative with an organic monomer and a method of forming the same. The ultrathin polymer film has a thickness of 10 nm or less, and can retain its film shape even after being separated from a substrate.
    Type: Grant
    Filed: April 21, 2005
    Date of Patent: August 24, 2010
    Assignee: Postech Academy-Industry Foundation
    Inventors: Kimoon Kim, Woo Sung Jeon, Dongwoo Kim, Dong Hyun Oh, Sang Yong Jon
  • Controlled release nanoparticle having bound oligonucleotide for targeted delivery
    Patent number: 7727969
    Abstract: The present invention relates to a conjugate that includes a nucleic acid ligand bound to a controlled release polymer system, a pharmaceutical composition that contains the conjugate, and methods of treatment using the conjugate. The controlled release polymer system includes an agent such as a therapeutic, diagnostic, prognostic, or prophylactic agent. The nucleic acid ligand that is bound to the controlled release polymer system, binds selectively to a target, such as a cell surface antigen, and thereby delivers the controlled release polymer system to the target.
