    摘要: A nanostructure includes (1) an inorganic nanoparticle core; (2) a first ligand, having a first chain length, bonded to the inorganic nanoparticle core; the first ligand having a charge; and (3) a second ligand, having a second chain length, bonded to the inorganic nanoparticle core; the second ligand is hydrophilic. The second chain length is longer than the first chain length such that varying a mole percent quantity of the first ligand does not substantially alter a hydrodynamic diameter of the nanostructure. Methods for making these nanostructures and their use in magnetic resonance imaging and management of inflammatory conditions are provided.
