Biomedical Applications of Carbon Nanotubes and the related Cellular Toxicity

Bellucci S., Balasubramanian C., Bergamaschi A., Bottini M., Magrini A., Mustelin T., INFN-Laboratori Nazionali di Frascati, IT

Carbon nanotubes, a form of carbon that did not exist in our environment before being manufactured possess unique chemical, physical, optical, and magnetic properties, which make them suitable for many uses in industrial products and [...]

Cluster assembled nanostructured TiO2 film mediates efficient and safe retroviral gene transduction in primary adult human melanocytes for ex-vivo gene therapy

Carbone R., Marangi I., Zanardi A., Lanfrancone L., Minucci S., Pelicci P.G., Giorgetti L., Clerici E., Bongiorno G., Piseri P., Milani P., European Institute of Oncology, IT

Primary human melanocytes represent the precursor cells to melanoma and also specific targets of inherited and acquired pigmentation disorders (1,3). The possibility to genetically manipulate these cells for biological studies or therapy has not been [...]

Nanotechnology in Italy: National Programs, Players and Activities

Mantovani E., Porcari A., AIRI-NanotecIT, IT

AIRI-Nanotec IT, the Italian focal point for nanotechnology, thanks to its extended network which include private enterprises, public R&D institutions and academia, will provide a comprehensive and up-to-date panorama of nanotechnology in Italy.The presentation will [...]

Gas Sensor Arrays by Supersonic Cluster Beam Deposition

Barborini E., Leccardi M., Bertolini G., Rorato O., Franchi M., Bandiera D., Gatelli M., Wegner K., Raso A., Garibbo A., Ducati C., Piseri P., Milani P., Tethis S.r.l., IT

Supersonic cluster beam deposition was employed to produce nanostructured thin films of transition metal oxides to be used as gas sensors. The cluster beam was generated by a pulsed microplasma cluster source equipped with aerodynamic [...]

The role of the synthetic procedure on the photoactivity of nanocrystalline TiO2

Ardizzone S., Bianchi C.L., Cappelletti G., Pirola C., Ragaini V., University of Milan, IT

The nanometer scale of the TiO2 plays a key role in affecting the photocatalytic performance of the material. In recent years a great deal of activity was dedicated, by the authors, to the study of [...]

Integrated Gas-Phase Manufacturing of Nanostructured Particulate Films

Wegner K., Piseri P., Bongiorno G., Vinati S., Pratsinis S.E., Milani P., Tethis S.r.l., IT

An integrated process for controlled one-step production of nanostructured particulate thin films is presented, combining gas-phase nanoparticle synthesis, aerodynamic particle manipulation, size selection and deposition. Such films find industrial application for instance in fuel cells, [...]

Innovative PMMA/CaCO3 Nanocomposites

Avella M., Errico M.E., Gentile G., INSTITUTE OF POLYMER CHEMISTRY AND TECHNOLOGY - CNR, IT

Innovative poly(methyl methacrylate) based nanocomposites filled with two kinds of calcium carbonate nanoparticles, coated with stearic acid and poly(butyl acrylate), were prepared. The influence of the nanoparticles nature and content on the chemical-physical properties of [...]

Characterization of Aluminum Nitride Nanostructures by XANES and FTIR Spectroscopies with Synchrotron Radiation

Bellucci S., Balasubramanian C., Cinque G., Marcelli A., Cestelli Guidi M., Piccinini M., Popov A., Soldatov A., Onorato P., INFN-Laboratori Nazionali di Frascati, IT

We investigated nano-systems of AlN synthesized by DC arc-plasma-induced melting of aluminum in a nitrogen–argon ambient. Actually, the reaction of molten Al with N2 gas yields on a water-cooled surface a mixture of both nanowires [...]
