Journal ArticleDOI
Accumulation, translocation and impact of TiO2 nanoparticles in wheat (Triticum aestivum spp.): Influence of diameter and crystal phase
Camille Larue,Julien Laurette,Nathalie Herlin-Boime,Hicham Khodja,Barbara Fayard,Barbara Fayard,Anne-Marie Flank,François Brisset,Marie Carrière,Marie Carrière +9 more
TL;DR: Comparing root accumulation and root-to-shoot translocation in wheat of anatase and rutile TiO(2)-NPs with diameters ranging from 14 nm to 655 nm suggests that only the smallest TiO (2) nanoparticles may be accumulated in wheat plants, although in limited amounts and that their impact is moderate.
Journal ArticleDOI
Titanium dioxide nanoparticle impact and translocation through ex vivo, in vivo and in vitro gut epithelia.
Emilie Brun,Frédérick Barreau,Frédérick Barreau,Frédérick Barreau,Giulia Veronesi,Barbara Fayard,Barbara Fayard,S. Sorieul,Corinne Chanéac,Christine Carapito,Thierry Rabilloud,Aloïse Mabondzo,Nathalie Herlin-Boime,Marie Carrière +13 more
TL;DR: In vivo and ex vivo data prove that TiO2-NPs would possibly translocate through both the regular epithelium lining the ileum and through Peyer’s patches, would induce epithelia impairment, and would persist in gut cells where they would possibly induce chronic damage.
Journal ArticleDOI
Localization and chemical forms of cadmium in plant samples by combining analytical electron microscopy and X-ray spectromicroscopy
Marie-Pierre Isaure,Barbara Fayard,Barbara Fayard,Géraldine Sarret,Sébastien Pairis,Jacques Bourguignon +5 more
TL;DR: In this paper, the chemical form(s) of cadmium was investigated using Cd LIII-edge (3538 eV) micro X-ray absorption near edge structure (μ-XANES) spectroscopy.
Journal ArticleDOI

TL;DR: The ID21 beamline (European Synchrotron Radiation facility, France) is a multi-analytical platform combining X-ray and infrared micro-probes, for characterization of elements, species, molecular groups and crystalline structures in complex materials.
Journal ArticleDOI
The scanning x-ray microprobe at the esrf "x-ray microscopy" beamline
TL;DR: In this paper, the strengths and weaknesses of X-ray microscopy and spectromicroscopy techniques are discussed and illustrated by examples in biology, materials science and geology.
