Contact angle and adsorption energies of nanoparticles at the air-liquid interface determined by neutron reflectivity and molecular dynamics

Francesco Stellacci, Javier Reguera Gomez, Mauro Moglianetti

Understanding how nanomaterials interact with interfaces is essential to control their self-assembly as well as their optical, electronic, and catalytic properties. We present here an experimental approach based on neutron reflectivity (NR) that allows the ...

Antibacterial activity of silver nanoparticles: A surface science insight

Francesco Stellacci

Silver nanoparticles constitute a very promising approach for the development of new antimicrobial systems. Nanoparticulate objects can bring significant improvements in the antibacterial activity of this element, through specific effect such as an adsorpt ...

Chemical challenges during the synthesis of MWCNT-based inorganic nanocomposite materials

László Forró, Arnaud Magrez, Endre Horvath

Multiwalled carbon nanotubes (MWCNTs) were successfully covered with metal oxides - such as TiO2, ZnO, Al2O3, SnO2, and In2O3 nanoparticles - with different preparation methods under solvent conditions. The applied synthesis techniques were impregnation, a ...

On-Chip Fabrication of Paclitaxel-Loaded Chitosan Nanoparticles for Cancer Therapeutics

Philippe Renaud, Arnaud Bertsch, Mohammad Mahdi Hasani-Sadrabadi, Jules John Vandersarl

The use of solvent-free microfluidics to fine-tune the physical and chemical properties of chitosan nanoparticles for drug delivery is demonstrated. Nanoparticle self-assembly is driven by pH changes in a water environment, which increases biocompatibility ...

Functionalization of Nanoparticles for Targeted Cancer Imaging and Diagnosis

Solène Marcelle Françoise Marie Passemard

At present time, cancer is the leading cause of death in developed countries. The medical imaging tools currently used in clinics such as radiology, nuclear magnetic resonance imaging, microscopy and endoscopy are not able to reach the sensitivity necessar ...

Bioavailability of inorganic nanoparticles to planktonic bacteria and aquatic microalgae in freshwater

Paul Bowen, Nadia Rachel Von Moos

Over the past few years, engineered nanomaterials (ENMs) have penetrated nearly every sector of modern life and their broad-scale use is steadily and rapidly increasing. The (expected) elevated levels of ENMs in the environment raise concerns with regard t ...
