New article by Dussert et al. in Frontiers in Toxicology

Quantum dots (QDs) are colloidal fluorescent semiconductor nanocrystals with exceptional optical properties. Their widespread use, particularly in light-emitting diodes (LEDs), displays, and photovoltaics, is questioning their potential toxicity. Read More

Iron particles of sizes between 6 and 20 nm forming aggregates of 57 ± 17 nm were synthesized by chemical reduction of iron precursors on the surface of montmorillonite (MMT). This active MMT-Fe powder was then uniformly distributed in a linear low-density polyethylene (LLDPE) matrix by extrusion at atmospheric conditions, as confirmed by wide-angle X-ray scattering (WAXS), which also detected a partial exfoliation of the nanoclays.

Nanotoxicology remains an important and emerging field since only recent years have seen the improvement of biological models and exposure set-ups towards real-life scenarios. Read More

New article by Annangi et al. in Particle and Fibre Toxicology

Cerium (Ce) is a rare earth element, rapidly oxidizing to form CeO2, and currently used in numerous commercial applications, especially as nanoparticles (NP). The potential health effects of Ce remain uncertain, but literature indicates the development of rare earth pneumoconiosis accompanied with granuloma formation, interstitial fibrosis and inflammation.

New article by Cotena et al. in Nanomaterials

Cerium dioxide nanomaterials (CeO2 NMs) are widely used in nano-based diesel additives to decrease the emission of toxic compounds, but they have been shown to increase the emission of ultrafine particles as well as the amount of released Ce. The Organization for Economic Cooperation and Development included CeO2 NMs in the priority list of nanomaterials that require urgent evaluation... Read More

New article by Slomberg et al. in Environmental Pollution

Nanoparticulate mineral UV filters, such as titanium dioxide (TiO2) nanocomposites, are being increasingly used in sunscreens as an alternative to organic UV filters. However, there is still a lack of understanding regarding their fate and behavior in aquatic environments and potential environmental impacts after being released from a bather’s skin during recreational activities.

New article by Rose et al. in NanoToday

Developing safe nanomaterials has become a major concern in all the industry sectors using advanced materials. However, there are very few initiatives addressing this issue. The SERENADE project, with its long-term funding scheme, provided a unique opportunity to foster a coordinated, yet diverse approach to investigate the safe-by-design development of nanomaterials in a variety of application fields, using a targeted set of inter-disciplinary case studies.

New article by Catalano et al. in Colloids and Surfaces A: Physicochemical and Engineering Aspects

Manufactured TiO2 nanoparticles are widely used in cosmetics as UV blockers. The environmental risk associated with these Engineered Nanomaterials (ENMs) strongly depends on their concentration, aggregation state and surface chemistry. Controlling these parameters in the sunscreen formulation is crucial in order to optimize the ENMs content and better understand their fate, transport, and toxicity at the product’s end-of-life.

New article by Eymard-Vernain et al. in Plos One

Due to the physicochemical properties of nanoparticles, the use of nanomaterials increases over time in industrial and medical processes. We herein report the negative impact of nanoparticles, using solid growth conditions mimicking a biofilm, on the ability of Bacillus subtilis to fight against a stress. Read More
