Development of novel analytical methods to trace small micro- and nanoplastics in food matrices
identified by Raman microspectroscopy. As a side supporting technique, atomic force microscopy (AFM) and transmission electron microscopy (TEM) have been employed to investigate the size, shape and the ...
Advances in the physicochemical characterization of nanoparticles in a regulatory context.
of optimizing sample (dispersion) and specimen (EM-grids) preparation will be demonstrated, application of conventional TEM for characterizing pristine materials will be shown, and the possibilities of ...
Identification and characterization of TiO2 nanoparticles in face masks by TEM
1866, Mountain View, CA 94042, p.17 (2022) Keywords: Agglomerates electron microscopy energy dispersive X-ray spectroscopy Face mask image analysis Nanoparticles particle size distribution STEMEDX TEM ...
Particle size analysis of pristine food-grade titanium dioxide and E 171 in confectionery products: Interlaboratory testing of a SP-ICP-MS screening method and confirmation with transmission electron microscopy.
electron microscopy (TEM) was used as a confirmatory technique and served as the basis for bias estimation. The optimisation of the sample preparation step showed that when this protocol was applied to the ...
