  • Patent number: 9801958
    Abstract: The present invention provides a safe polymer nanoparticle composite with few side effects, and an MRI contrast agent incorporating said polymer nanoparticle composite. The polymer nanoparticle composite is capable of specifically accumulating on a tumor tissue to selectively extract the tissue, exhibiting high contrast even when used in small amounts, and enabling imaging over prolonged periods of time. This polymer nanoparticle composite is characterized by containing a block copolymer that includes a non-charged hydrophilic polymer chain segment and an anionic polymer chain segment, and MnCaP.
    Type: Grant
    Filed: August 22, 2014
    Date of Patent: October 31, 2017
    Assignee: THE UNIVERSITY OF TOKYO
    Inventors: Kazunori Kataoka, Nobuhiro Nishiyama, Horacio Cabral, Peng Mi, Akihiro Kishimura, Yutaka Miura, Ichio Aoki, Daisuke Kokuryo, Tsuneo Saga
