Cell Culture Media elicit a different dynamic Formation of Protein-NP Complexes: Effects on the Cellular Response

Sabella S., Maiorano G., Sorce B., Brunetti V., Malvindi M.A., Cingolani R., Pompa P.P., Italian Institute of Technology, IT

We show that the dynamics of proteins-NP interactions are differently mediated by different cellular media, which are the liquid environments where NPs encounter cells. We used, as a model, spherical NPs (citrate-capped gold nanoparticles, AuNPs) [...]

Effect of Carbon Nanotubes on Chinese Hamster Ovarian Cells

Chen H.H., Chen M., Luca J.A., Chen H.H., Chen M., Point Loma Nazarene University, US

We report the effect of carbon nanotubes at the cellular level using purified single-walled carbon nanotubes (SWNTs) resuspended in physiological compatible phosphate buffered saline (PBS) and systematically study its impact on Chinese Hamster Ovarian (CHO) [...]

In vivo nanotoxicity assessment: the role of size, surface coating, nanostructuration and dose-metrics

Vecchio G., Galeone A., Brunetti V., Maiorano G., Malvindi M.A., Sabella S., Cingolani R., Pompa P.P., Italian Institute of Technology, IT

The growing use of nanomaterials in commercial goods and as novel carriers for drug delivery is generating increasing questions about possible risks for human health and environment, due to the lack of an in-depth assessment [...]

Nanoparticle Release from Polymer Nanocomposites Used for Potable Water Infrastructure and Food Packaging: Current Progress & Beyond

Whelton A.J., Duncan T.V., Koontz J.L., Nguyen T., University of South Alabama, US

Engineered nanoparticles (ENP) are increasingly being integrated into polymeric infrastructure and food packaging materials worldwide. ENPs can improve product strength, extend infrastructure service life, and increase a polymer’s antimicrobial resistance and oxygen barrier properties. While [...]

Cytotoxicity Assessment of Human Lung Alveolar Cell Exposed to Nanoparticles and Polycyclic Aromatic Hydrocarbons Exhausted from Motorcycle

Chien S.M., Huang Y-J, Chuang C.C.Y., Hsiao I.L., Kuo Y.F., National Tsing Hua University, TW

The potential harmfulness of traffic pollutants, particulate matter (PM) and polycyclic aromatic hydrocarbons (PAHs), were elevated with the increment of motocycles. However, the toxicology of the nanoparticulate and particle-PAHs (p-PAHs) has rarely been evaluated in [...]

Potential Insurance Coverage Issues Arising from Nanotechnology: Big Risks Could Come in Small Packages

Fink A.J., Howrey LLP, US

Businesses involved with nanotechnology should undertake risk management that assesses the potential losses that could arise as a result of nanotechnology and develop a broad insurance coverage program that takes these risks into account. Some [...]

California’s Efforts to Safe and Responsible Nanotechnologies: Information Call-in from Manufacturers of Nanometals and Oxides

Kang H.Y., California Environmental Protection Agency, US

The nanotechnologies and their applications encompass many areas. However, because of their unique properties, nanomaterials might have the potential to adversely effects to human health and the environment. The potential risks of nanomaterials such as [...]

The Mechanism of Mediated Electrochemical Dissolution of Semiconducting Metal Oxide Particle

Inoue A., Japan Atomic Energy Agency,Tokai, JP

The dissolution of plutonium dioxide (PuO2) is of a fundamental importance from the point of view of energy as well as environment. In this work the mechanism of the mediated electrochemical dissolution of semiconducting plutonium [...]

Cell damage by energy saving light bulbs

Mironava T., Rafailovich M.H., SUNY at Stony Brook, US

The growing concern regarding green house gas emissions during power generation has increased awareness regarding energy conservation. Next to transportation, lighting is one of the major sources of energy consumption. Compact fluoresce light bulbs (CFL) [...]
