2-nm gold nanoclusters coated with Zn(II) complexes bearing auxiliary hydrogen bond donors act as multivalent catalysts capable of promoting the hydrolysis of model phosphate diesters with… (More)
Silica nanoparticles (60 nm diameter) doped with fluorescent dyes and functionalized on the surface with thiol groups have been proved to be efficient fluorescent chemosensors for Pb2+ ions. The… (More)
For samples whose NMR spectra are dominated by the broad signals of macromolecules or functionalized nanoparticles, transverse relaxation (T(2)) spectral editing lends itself to a precise… (More)
Silica nanoparticles (about 15 nm diameters), which contain a derivative of 6-methoxy-8-(p-toluensulfonamido)-quinoline (TSQ) as a Zn(II) fluorescent probe covalently linked to the silica network,… (More)
A fluorescence nanosensor for Cu2+ ions has been obtained by surface functionalization of silica particles with trialkoxysilane derivatized ligand and fluorescent dye.
Monolayer protected gold nanoparticles (MPGN) coated with metal chelating groups were prepared. In the presence of Ce(IV), the MPGN proved to be highly active in promoting the hydrolytic cleavage of… (More)
The self-organization of Zn(II) complexes on the surface of 1.6-nm diameter gold nanoparticles (nanozymes) allows the spontaneous formation of multiple bimetallic catalytic sites capable to promote… (More)
A series of cis-cis-triaminocyclohexane Zn(II) complex-anthraquinone intercalator conjugates, designed in such a way to allow their easy synthesis and modification, have been investigated as… (More)
Gd(3+) ions, once bound to the monolayer of organic molecules coating the surface of gold nanoparticles, produce a paramagnetic relaxation enhancement (PRE) that broadens and eventually cancels the… (More)
The Na+ transporting properties of the first member of a new class of artificial ionophores, based on a C2-symmetric polyhydroxylated steroid dimer, are described.
