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 signals of the nuclear spins located nearby (within 1.6 nm distance). In the case of nanoparticles coated with mixed monolayers, the signals arising from the(More)
Lanthanide ions Yb(3+) and Tb(3+), once bound to the monolayer of organic molecules coating the surface of gold nanoparticles, induce pseudo-contact shifts on the signals of nearby nuclear spins. This not only allows the investigation of the average structure of the ligands in the monolayer but also the mapping of the position of organic molecules bound to(More)
One of the most daunting challenges of nanomedicine is the finding of appropriate targeting agents to deliver suitable payloads precisely to cells affected by malignancies. Even more complex is the ability to ensure that the nanosystems enter those cells. Here, we use 2 nm (metal core) gold nanoparticles to target human hepatocellular carcinoma (HepG2)(More)
F has been studied in the reaction 90-MeV He+ " 'Ag. Although the yields of the heavier elements are orders of magnitude less than for He, the energy spectra, charge, and angular distributions indicate that an equilibrium statistical process is responsible for the production of these heavy nuclei in the backward hemisphere. The typical compound-nucleus(More)
