発明の名称 (英語) POLYMER NANOPARTICLE COMPOSITE AND COMPOSITION FOR MRI IMAGING INCLUDING SAME
発明の概要(英語) The present invention provides a safe polymer nanoparticle composite with few side effects, and a MRI imaging 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.
