    摘要： The present application discloses nanoparticles, particularly nanoparticles of superparamagnetic iron oxide, which find utility in iron therapy and diagnostic imaging such as magnetic resonance (MR). The disclosed nanoparticles have been treated with an α-hydroxyphosphonic acid conjugate containing polyethylene glycol as a hydrophilic moiety to render the nanoparticles sufficiently hydrophilic to find utility in diagnostic imaging. Among the modified hydrophilic nanoparticles disclosed are those in which the hydrophilic moieties of the modifying conjugate are polyethylene oxide-based polymers and have a molecular weight greater than 5,000 dalton and less than or equal to about 30,000 daltons. Surprisingly, these nanoparticles have a more rapid and complete processing in liver of retained nanoparticles when compared to similar nanoparticles in which the PEG-based hydrophilic moiety has a molecular weight less than 5,000.

    摘要： A method of sterilizing a nanoparticle preparation at a high temperature is provided. A plurality of nanoparticles are purified to form the preparation, wherein the nanoparticles comprise at least a core and a shell and the shell comprises one or more ligand species attached to the core. The nanoparticle preparation is made by a purified nanoparticle composition, a carrier fluid and an excess of the one or more ligand species not attached to the core. The ligand species attached to the core and the excess ligand species added after purification are structurally identical. The nanoparticle preparation provided by the present invention may be used as contrast agents in medical imaging techniques such as X-ray and magnetic resonance imaging.
