  • Functionalized magnetic nanoparticle, a catalyst, a method for forming C—C bonds
    Patent number: 10125159
    Abstract: A functionalized magnetic nanoparticle including an organometallic sandwich compound and a magnetic metal oxide. The functionalized magnetic nanoparticle may be reacted with a metal precursor to form a catalyst for various C—C bond forming reactions. The catalyst may be recovered with ease by attracting the catalyst with a magnet.
    Type: Grant

  • FERRIC ION DETECTION METHOD
    Publication number: 20180217152
    Abstract: Gold nanoparticles functionalized with thiolated, bidentate Schiff base ligands. The Schiff base ligands form a ligand monolayer surrounding and binding to the surface of a gold nanoparticle core through Au—S linkages. The functionalized gold nanoparticle composites have a spherical shape, an average diameter of 7-15 nm and a narrow particle size distribution. Methods of assessing these functionalized gold nanoparticle composites as fluorescent probes in Fe(III) chemosensing applications, methods of preparing the functionalized gold nanoparticle composites and methods of detecting Fe(III) ions with the same are also provided.
    Type: Application
