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 ...

Human absorption of silver ENM: through particles or ions?

collected. After 24 hours, selected tissues were sampled and total Ag concentrations were measured by ICP- MS. After treatment by IV injection with the silver salt, largest Ag concentrations were found in the ...

TEM and SP-ICP-MS analysis of the release of silver nanoparticles from decoration of pastry.

particles was studied by electron diffraction and chemical information was obtained by combining HAADF- STEM imaging with EDX spectroscopy and mapping. The TEM results were confirmed by SP- ICP- MS. The ...
