  • Optical-imaging probe for detecting sentinel lymph nodes which contains a composite of poly-gamma-glutamic acid and an optical-imaging dye
    Patent number: 9623121
    Abstract: The present invention relates to an optical imaging probe for detecting a sentinel lymph node, which contains a complex of poly-gamma-glutamic acid and an optical imaging dye, and more particularly to an optical imaging probe for detecting a sentinel lymph node, which contains a poly-gamma-glutamic acid/optical imaging dye complex that, when injected subcutaneously in vivo, remains in the sentinel lymph node for a relatively long period of time and has a low tendency to migrate to other lymph nodes. The present invention provides a poly-gamma-glutamic acid/fluorescent dye complex, which contains no radiopharmaceutical and is harmless to the human body. The use of the poly-gamma-glutamic acid/fluorescent dye complex makes it possible to accurately detect the position of a sentinel lymph node in real time without concerns about radioactive contamination.

  • High-sensitivity magnetic resonance imaging nano-contrast agent based on an anionic polymer and cationic polymer ion complex, and a production method therefor
    Patent number: 9138491
    Abstract: The present invention relates to a nano-composite containing anionic and cationic polymers and a method for preparing thereof, and more particularly to a poly-gamma-glutamic acid (?-PGA)/chitosan/manganese iron oxide nanoparticle composite prepared by encapsulating iron oxide-based nanoparticles in a ?-PGA/chitosan polymer composite using the ionic self-assembly properties of poly-gamma-glutamic acid (?-PGA) and chitosan, which are biocompatible polymer materials, and to a method for preparing thereof. The present invention provides a magnetic resonance imaging nano-contrast agent based on a nanoparticle composite including iron oxide-based nanoparticles encapsulated in a self-assembled composite of anionic poly-gamma-glutamic acid (?PGA) and cationic chitosan.
