    RGD-targeted MnO nanoparticles as T1 contrast agents for cancer imaging – the effect of PEG length in vivo

    , J. Mater. Chem. B

    As magnetic resonance imaging (MRI) contrast agents, T1 Gd3+ chelates are generally the preferred option for radiologists over T2 iron oxide nanoparticles. The main reason for the popularity of T1 agents is the easier interpretation of T1-weighted MR images. However, the chemical versatility of nanoparticulate platforms makes them ideal candidates for the next generation of targeted MRI contrast agents. In this context, we present herein the design and preparation of a nanoparticulate contrast agent based on MnO, which presents T1 contrast enhancement properties as well as nanoparticle formulation. Functionalization of MnO nanoparticles with the extensively studied RGD peptide was used to target tumours over-expressing the αvβ3 integrin. PEG (polyethylene glycol) molecules were used to increase the blood half-life of the nanoparticles in vivo, and the effect of different PEG lengths on the final contrast on MR images was investigated.

    8-quinolinolato gallium complexes: iso-selective initiators for rac-lactide polymerization

    , Inorganic Chemistry, Vol: 52, Pages: 12561-12567, ISSN: 1520-510X

    The synthesis and characterization of a series of 8-quinolinolato gallium complexes is presented, and the complexes are analogous to a series of aluminum complexes previously reported. The complexes have been shown to be active initiators for the ring-opening polymerization of rac-lactide. High degrees of polymerization control are demonstrated, as exemplified by the linear evolution of molecular weight as the polymerization progresses, narrow polydispersity indices, and molecular weights corresponding to those predicted on the basis of initiator concentration. Some of the initiators show iso-selective polymerization of rac-lactide, with Pi = 0.70. The polymerization rates have been monitored, and the pseudo first-order rate constants are compared to those of analogous aluminum compounds. The 8-quinolinolato gallium initiators show rates approximately 3 times higher than those of the series of aluminum compounds, while maintaining equivalently high iso-selectivity (Pi = 0.70) and polymerization control.
