Manufactured metal and metal-oxide nanoparticles: Properties and perturbing mechanisms of their biological activity in ecosystems
Jean-Yves Bottero,Mélanie Auffan,Jérôme Rose,Catherine Mouneyrac,Céline Botta,Jérôme Labille,Armand Masion,Antoine Thill,Corinne Chanéac +8 more
TL;DR: In this article, strong relations between particular physical chemical properties of very small nanoparticles (size < 30 nm) and biological activity perturbations were shown. But the results were limited to the case of small size nanoparticles.
Journal ArticleDOI
Using a holistic approach to assess the impact of engineered nanomaterials inducing toxicity in aquatic systems.
TL;DR: It is concluded that a holistic approach is urgently needed to fulfill the knowledge gap regarding the safety of discharged ENMs and establish a quantitative and reliable system to predict such outcomes.

Evidence and uptake routes for Zinc oxide nanoparticles through the gastrointestinal barrier in Xenopus laevis
Renato Bacchetta,Elisa Moschini,Nadia Santo,Umberto Fascio,Luca Del Giacco,Stefano Freddi,Marina Camatini,Paride Mantecca +7 more
TL;DR: NZnOs embryotoxicity was confirmed to be crucially mediated by the NPs' reactivity rather than their dissolved ions, and their ability to overwhelm the intestinal barrier must be taken into high consideration for a future design of safer ZnO NPs.
Journal ArticleDOI
Short-term effects of TiO2, CeO2, and ZnO nanoparticles on metabolic activities and gene expression of Nitrosomonas europaea
TL;DR: The TEM imaging and the synchrotron X-ray fluorescence microscopy of the NPs impacted cells revealed the increase of the corresponding intracellular Ti, Ce or Zn contents and suggested the intrACEllular NP accumulation.

Risk Analysis Based on Data and Crisis Response Beyond Knowledge : Proceedings of the 7th International Conference on Risk Analysis and Crisis Response (RACR 2019), October 15-19, 2019, Athens, Greece
TL;DR: In this article, two criteria are suggested to inspect whether a model of geospatial information diffusion is valid to fill in the missing observation in a gap unit, and the valid radiance determined by the maximum distance between the units of the sample point passed the test.

Nanotoxicology: An Emerging Discipline Evolving from Studies of Ultrafine Particles
TL;DR: Results of older bio-kinetic studies with NSPs and newer epidemiologic and toxicologic studies with airborne ultrafine particles can be viewed as the basis for the expanding field of nanotoxicology, which can be defined as safety evaluation of engineered nanostructures and nanodevices.

Probing the Cytotoxicity Of Semiconductor Quantum Dots.
TL;DR: This work found that CdSe-core QDs were indeed acutely toxic under certain conditions and modulated by processing parameters during synthesis, exposure to ultraviolet light, and surface coatings, and suggests that cytotoxicity correlates with the liberation of free Cd2+ ions due to deterioration of the Cd Se lattice.
