EFSA Project on the use of New Approach Methodologies (NAMs) for the hazard assessment of nanofibres. Lot 1, nanocellulose oral exposure: gastrointestinal digestion, nanofibres uptake and local effects
indications for genotoxicity were obtained. Finally, no formation of smaller particles following colonic fermentation of NC was observed. For the integration of these results in regulatory hazard assessment of ...

Sentinel-2 Satellite and Hysplit Model Show that Local Cereal Harvesting Substantially Contributes to Peak Alternaria Spore Concentrations
contribution of cereal harvesting to peak Alternaria spore concentrations. Daily Alternaria spores were collected using Hirst-type traps in 12 sites in Europe for the period 2016-2018. Hybrid Single-Particle ...
Evaluation of the types, efficient use and health risks of application of silver-based biocides to provide antimicrobial properties to face masks applied during the Covid-19 crisis
distributed in the matrix of the fibers, (iii) Ag NP and large silver particles at the surface of, or close to cotton fibres in face masks containing polycationic polymers binding Ag+ ions, and (iv) a coating ...

Vleminckx; Eveline Verleysen Source: Sciensano, Elsene, Belgium, p.50 (2021) Accession Number: D/2021/14.440/72 Abstract: In situ analysis of titanium dioxide (TiO2) particles in face masks demonstrated the ...
A systematic evaluation of Flow Field Flow Fractionation and single-particle ICP-MS to obtain the size distribution of organo-mineral iron oxyhydroxide colloids.
Field Flow Fractionation iron oxyhydroxide colloids particle size distribution Single particle ICP-MS Abstract: Colloidal iron(III) oxyhydroxides (FeOx) are important reactive adsorbents in nature. This ...
Evaluation of a TEM based Approach for Size Measurement of Particulate (Nano)materials.
properties, including particle size, shape, and agglomeration state. The measurement of the median value of the minimal external particle diameter distribution was intra-laboratory validated. The validation ...
Evaluation of a TEM based Approach for Size Measurement of Particulate (Nano)materials
preparation, imaging, and image analysis, and it was evaluated on a series of certified reference materials and representative test materials with varying physical properties, including particle size, shape, and ...
Nanomaterials for food applications: Analytical challenges and practical solutions for enforcing labeling of nanoingredients in food products in the European Union
Nanoparticles Single particle ICP-MS Abstract: Food ingredients present in the form of engineered nanoparticles (NP s) require specific labeling as “nano” in the European Union. Enforcing proper labeling of ...
Multivalent binding of herpesvirus to living cells is tightly regulated during infection.
8 (2018) Abstract: Viral infection, initiated by the landing of a virion on a cellular surface, is largely defined by the preliminary interactions established between viral particles and their receptors at ...
