    E.-K. Lim, E. Jang, B. Kim, J. Choi, K Lee, J.-S. Suh, Y.-M. Huh, S. Haam
    J. Mater. Chem., 2011, 21, 12473
    We fabricated dextran-coated magnetic nanoclusters (Dex-MNCs) for targeted magnetic resonance (MR) imaging of inflammatory macrophages. Dex-MNCs were prepared through encapsulation of hydrophobic magnetic nanocrystals (MNCs) by pyren...

  50. 073. Highly sensitive phototransistor with crystalline microribbons from new π-extended pyrene derivative via solution-phase self-assembly

    Y. S. Kim, S. Y. Bae, K. H. Kim, T. W. Lee, J. A. Hur, M. H. Hoang, M. J. Cho, S. J. KIm, Y. Kim, M. KIm, K. Lee, S. J. Lee, D.-H. Choi
    Chem. Commun., 2011, 47, 8907
    A new pyrene-cored π-conjugated molecule has been synthesized through Sonogashira coupling reaction. The single-crystalline microribbon-based FET exhibited the highest mobility of 0.7 cm2 V−1 s−1 (Ion/Ioff > 106). Single-cry...

  52. 071. pH-sensitive Drug Triggering Magnetic Nanoparticles for Cancer Therapy Guided by Molecular Imaging via MRI

    E.-K. Lim, Y.-M. Huh, J. Yang, K. Lee, J.-S. Suh, S. Haam
    Adv. Mater., 2011, 23, 2436
    pH-sensitive drug-delivering magnetic nanoparticles (DMNPs) have been developed as theragnostic nanocarriers that release doxorubicin (DOX) under acidic conditions within cancer cells. The drug release kinetics of the DMNPs, combined...

    070. Characteristics of gadolinium oxide nanoparticles as contrast agents for terahertz imaging

    D.-K. Lee, H. Kim, T. Kim, B. Cho, K. Lee, J.-H. Son
    J. Infrared Milli Terahz Waves, 2011, 32, 506
    For the application of gadolinium oxide (Gd2O3) nanoparticles as terahertz contrast agents, their optical properties in a solvent were studied using terahertz time-domain spectroscopy. The power absorption and refractive index of the samples...
