Agglomeration of titanium dioxide nanoparticles increases toxicological responses in vitro and in vivo
exposed to these suspensions for 24 h and endpoints such as cytotoxicity, total glutathione, epithelial barrier integrity, inflammatory mediators and DNA damage were measured. Large agglomerates of 17 nm ...
Physicochemical Characterization of the Pristine E171 Food Additive by Standardized and Validated Methods.
for use as a food colorant in the European Union. The application of E171 in food has become an issue of debate, since there are indications that it may alter the intestinal barrier. This work applied ...
Is aggregated synthetic amorphous silica toxicologically relevant?
significantly relevant from a nanotoxicological perspective.This knowledge gap greatly afects the safety assessment and regulation of NM s, such as synthetic amorphous silica (SAS). SAS is used in a large panel ...
A systematic evaluation of Flow Field Flow Fractionation and single-particle ICP-MS to obtain the size distribution of organo-mineral iron oxyhydroxide colloids.
detection limit for FeOx of about 32-47 nm. The distribution of hydrodynamic diameters of goethite particles detected with FlFFF, NTA and DLS were similar but the values were twice as large as the Fe cores of ...
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.
introduce a new method to force-probe multivalent attachment directly on living cells, and we show, for the first time, direct evidence of a new mechanism by which a herpesvirus surface glycoprotein acts as ...
Short-term biodistribution and clearance of intravenously administered silica nanoparticles
concerns have been raised about potential adverse effects of synthetic amorphous silica, commonly used as food additive (E551), since silica nanoparticles have been detected in food containing E551. We ...
