Title: Synthesis of gadolinium carbonate-conjugated-poly(ethylene)glycol (Gd{sub 2}(CO{sub 3}){sub 3}@PEG) particles via a modified solvothermal method

PEGylated gadolinium carbonate ((Gd{sub 2}(CO{sub 3}){sub 3})@PEG) powder was successfully synthesized by a modified solvothermal method. The synthesized products were characterized by means of X-ray diffraction (XRD), Fourier Transform Infrared spectroscopy (FTIR), Scanning Electron Microscopy (SEM), and Energy Dispersive X-ray Spectroscopy (EDS). A systematic change in the chemical surface composition, crystallinity and size properties of the Gd{sub 2}(CO{sub 3}){sub 3}@PEG particles was observed by increasing the reaction time at 5 hours, 7 hours, and 8 hours. The corresponding XRD patterns showed that the Gd{sub 2}(CO{sub 3}){sub 3} particles had hexagonal symmetry (JCPDS No. 37-0559) with a crystallite size of 3.5, 2.9, and 4.6 nm. FTIR spectra showed that the Gd{sub 2}(CO{sub 3}){sub 3})@PEG particles were formed with the PEG as carbonyl and hydroxyl group attached to the surface. SEM analysis showed that the Gd{sub 2}(CO{sub 3}){sub 3})@PEG particles had a flake-like morphology of homogeneous sized particles and agglomerates. EDS analysis confirmed the presence of constituent Gd{sub 2}(CO{sub 3}){sub 3} elements.
