Patents by Inventor Eisuke Mizuguchi

Eisuke Mizuguchi has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Stabilized inorganic nanoparticle, stabilized inorganic nanoparticle material, method for producing stabilized inorganic nanoparticle, and method for using stabilized inorganic nanoparticle
    Patent number: 7875352
    Abstract: A stabilized inorganic nanoparticle which is stabilized by bonding protective ligands to a surface of an inorganic nanoparticle, wherein one part of binding sites on the surface of the inorganic nanoparticle are bonded to the protective ligand, the other part of the binding sites remain as a free site not bonded to the protective ligand, and satisfies the condition that the amount of the protective ligand bonded to the inorganic nanoparticle is a critical amount or the condition that the form of modifying the surface of the inorganic nanoparticle by the protective ligand is a critical modification form. According to the present invention, there is provided a stabilized inorganic nanoparticle that is stabilized by a protective ligand and can be rapidly functionalized with ease by bonding a functional ligand thereto.
