Engineered nanoparticles are smaller than 100 nm and designed to improve or achieve new physico-chemical properties. Consequently, also toxicological properties may change compared the parent compound. We examined developmental neurobehavioral effects following maternal exposure a nanoparticulate UV-filter (UV-titan L181).Time-mated mice (C57BL/6BomTac) were exposed by inhalation 1h/day 42 mg/m(3) aerosolized powder (1.7.10(6) n/cm(3); peak-size: 97 nm) on gestation days 8-18. Endpoints...
Abstract Summary : With the aid of layer multiplying coextrusion techniques, polymer composites comprising up to thousand uniform and alternating layers polyethylene terephthalate (PET) polycarbonate (PC) were produced. Morphology micromechanical deformation processes in these investigated by means transmission electron microscopy (TEM) atomic force (AFM). In particular, effect thickness individual on large strain micromechanisms was analyzed. On decreasing layers, a transition mechanism...
Thin polymer films containing metal nanoparticles were irradiated with ultrashort, linearly polarized laser pulses. As result of irradiation, nanostructural changes occur in a type periodically arranged, line-like areas modified particle size and shape distribution. The periodic formation this nanocomposite material is observed only for small filling factor range, which can be attributed to the percolation region or nearby. Transmission (also cross section) scanning electron microscopy...
Abstract Background Physiologically based kinetic models facilitate the safety assessment of inhaled engineered nanomaterials (ENMs). To develop these models, high quality datasets on well-characterized ENMs are needed. However, there at present, several data gaps in systemic availability poorly soluble particles after inhalation. The aim present study was therefore to acquire two comparable parametrize a physiologically-based model. Method Rats were exposed cerium dioxide (CeO 2 , 28.4 ±...
This document is a collection of three JRC Technical Reports that together form the “NanoDefine Methods Manual”, which has been developed within NanoDefine project ‘Development an integrated approach based on validated and standardized methods to support implementation EC recommendation for definition nanomaterial’, funded by European Union’s 7th Framework Programme, under grant agreement 604347. The overall goal was Commission Recommendation nanomaterial (2011/696/EU). empirical approach,...
Correction Some statements in our paper [1] are incorrect, below find corrections. Table one, Zirkonium The content of the UV Titan was miscalculated by a factor 10. correct number is therefore 0.86% (and not 8.65%). P. 12, 1 column (In discussion) For calculation retained amount titanium, some inconsistencies appear text regarding titanium vs. studied particle Titan, leading to overestimation dose. and numbers given below: Assuming each animal inhaled 1.8 L/hr with concentration 42.4 mg/m...
Our work aimed to examine nanoparticle levels in 69 distinct pooled mussel samples along the Norwegian coastline, considering from different environmental contexts, including natural locations, potentially polluted hotspots, and farms. Single-particle ICP-MS was utilized determine particle mass number concentrations at environmentally relevant addition total content of 11 elements: aluminum, barium, cerium, copper, iron, manganese, lead, silicon, silver, titanium, zirconium. Results showed...
This paper presents the concept of a novel adaptable sensing solution currently being developed under EU Commission founded PHOTONGATE project. will allow to quantify multiple analytes same or different nature (chemicals, metals, bacteria, etc.) in single test with levels sensitivity and selectivity at/or over those offered by current solutions. relies on two core technologies: bio-chemical technology (molecular gates) which confer specificity and, therefore, capability be analyte interest,...
Abstract There is an urgent need to apply effective, data-driven approaches reliably predict engineered nanomaterial (ENM) toxicity. Here we introduce a predictive computational framework based on the molecular and phenotypic effects of large panel ENMs across multiple in vitro vivo models. Our methodology allows for grouping multi-omics combined with robust toxicity tests. Importantly, identified novel mRNA-based markers extensively replicated them independent datasets. We found that models...
