Front Cover: The image represents Polymers in Biomedicine and Electronics—a collage by Kataoka and co-workers and Meerholz and co-workers. The top-left half shows high-density poly(ethylene glycol)-coated iron oxide/gold core/shell nanoparticles that can accumulate in tumors, facilitating negative enhancement of the tumor site in T2-weighted MR images. Novel hole-transporting polymers with tetraarylbenzidines or tetraarylphenylenediamines as charge-transporting units with a non-conjugating fluorine bridge are presented in the bottom-right image. Crosslinkable derivatives are promising candidates for solution-processed multilayer organic light-emitting diodes (OLEDs) and will be incorporated into highly efficient green-light-emitting phosphorescent OLEDs for improved charge injection. Further details can be found in the articles by M. Kumagai, T. K. Sarma, H. Cabral, S. Kaida, M. Sekino, N. Herlambang, K. Osada, M. R. Kano, N. Nishiyama, and K. Kataoka* on page 1521 and by J. Schelter, G. F. Mielke, A. Köhnen, J. Wies, S. Köber, O. Nuyken,* and K. Meerholz* on page 1560.
