TL;DR: This study compares sizing of four silver nanoparticle dispersions by spICPMS to four established sizing techniques: dynamic light scattering, differential centrifugal sedimentation, nanoparticle tracking analysis, and TEM, and shows that sp ICPMS is able to size silver nanoparticles, across different sizes and particle number concentrations, with accuracy similar to the other commercially available techniques.

TL;DR: In this article, the authors compared hydrodynamic chromatography (HDC) and asymmetrical flow field flow fractionation (AF4), both coupled with inductively coupled plasma mass spectrometry (ICP-MS), in their capacity to detect, quantify, and characterize nanoparticles.

TL;DR: The present work describes the advantages achieved when interfacing sensitive and elemental specific detectors, such as inductively coupled plasma atomic emission spectroscopy and mass spectrometry, to FFF separation analysis to provide high resolution nanoparticle sizing and compositional analysis at the μg/L concentration level.

TL;DR: The authors' objective was to utilize environmentally relevant bioassays and study the impact, bioaccumulation, tissue distribution, uptake, and depuration of AgNPs on a sediment-dwelling invertebrate, Lumbriculus variegatus.
