Screening for nanoparticles in complex matrices within a regulatory framework: are we there yet?
samples of E174 and ten food items containing E174 were investigated for their number-based size distribution of Ag particles. The food items were as well investigated for their total Ag content. Single ...
Validation of a particle tracking analysis method for the size determination of nano- and microparticles.
mean of the number-weighted particle size distribution, varied from about 10% to 12%. For the nominal 50 nm polystyrene material, the relative expanded uncertainty of the arithmetic mean of the particle ...
Physical Characterization of Nanomaterials in Dispersion by Transmission Electron Microscopy in a Regulatory Framework
specimens to obtain a representative distribution of particles on the grid is discussed. The application of TEM imaging methods, electron diffraction and analytical TEM to obtain complementary information on ...
