Agglomeration of titanium dioxide nanoparticles increases toxicological responses in vitro and in vivo
TiO2 induced stronger responses than small agglomerates for glutathione depletion, IL-8 and IL-1β increase, and DNA damage in THP-1, while no effect of agglomeration was observed with 117 nm TiO2. In ...
Is aggregated synthetic amorphous silica toxicologically relevant?
human bronchial epithelial (HBE), colon epithelial (Caco2) and monocytic cells (THP-1). We observed that the de-aggregated suspension (DE- AGGR), predominantly composed of nano-sized aggregates, induced ...
Evaluation of a TEM based Approach for Size Measurement of Particulate (Nano)materials.
range of 1-7% and an expanded measurement uncertainty in the range of 7-20% were obtained, depending on the material and image analysis mode. No bias was observed when assessing the trueness of the ...
Evaluation of a TEM based Approach for Size Measurement of Particulate (Nano)materials
in the range of 7–20% were obtained, depending on the material and image analysis mode. No bias was observed when assessing the trueness of the approach on the certified reference materials ERM- FD100 ...
Toxicology of silica nanoparticles: an update
effects were mainly observed in acutely exposed animals, while no significant signs of toxicity were noted in chronically dosed animals. The correlation between in vitro and in vivo toxicity remains less ...
