Abstract

Featured on this month′s cover are the results of collaborative work between the research group at the University Nova of Lisbon, Faculty of Science and Technology, BIOSCOPE-NanOmics in Portugal, and the group at the University of Santiago de Compostela, Faculty of Chemistry in Spain. The cover picture represents the ability of silver and gold nanoparticles to form 1D nanostructured materials in the presence of polyamine ligands. These self-assembled nanoparticles are able to sense Hg2+ metal ions in water and can potentially be used as chromogenic and fluorogenic sensors. For more details, see the Full Paper on page 200 ff.
