  • Patent number: 9474810
    Abstract: 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 ?-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.

  • Patent number: 9120031
    Abstract: Embodiments of the invention provide a composition of a particulate coformulation which includes particles containing an active substance and an additive, wherein each particle contains a relative additive concentration increasing radially outwards from a particle center to a particle surface along a finite gradient. In one example, the particle surface is an additive-rich surface without a distinct physical boundary between the particle center and the particle surface. The relative additive concentration may have a continuous rate of change across the finite gradient. In some examples, an active substance: additive ratio of the particle surface is sufficiently low to form a protective surface layer around the active substance. Generally, the particle surface is free of the active substance.
