Abstract

COVER PICTURE: Adrian Fernandez-Lodeiro, Javier Fernandez-Lodeiro, Cristina Nunez*, Rufina Bastida, Jose Luis Capelo, and Carlos Lodeiro* The cover picture shows the formation of one-dimensional nanochains of silver nanoparticles (AgNPs) upon addition of a polyamine molecular linker. In the present work, the binding ability of this linker was exploited, bearing different functional groups, which favors the self-assembly of silver and gold nanoparticles (AuNPs) into one-dimensional nanochains in aqueous solution. These nanochains visually resemble the artistic work of "calceteiros" (pavers) to build the "calcada Portuguesa" (Portuguese pavements) in Portugal (Photography "calcada Portuguesa", Jose M. G. Pereira). Polyamine ligands are very versatile materials due to their water solubility and flexibility. The study of AgNPs and AuNPs in one-dimensional nanostructured formations are finally used as new sophisticated heavy metal (Hg(2+)) ion chemosensors. For more details, see the Full Paper by Carlos Lodeiro, Christina Nunez and co-workers, on p. 200 ff.
