TL;DR: This paper presents a practical guide on how to count and size nanoparticles using spICPMS, and an alternative protocol is provided for determining particle size that broadens the applicability of the technique to all types of inorganic nanoparticles.
Single particle inductively coupled plasma-mass spectrometry: a performance evaluation and method comparison in the determination of nanoparticle size.

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.

Synchrotron X-ray 2D and 3D elemental imaging of CdSe/ZnS quantum dot nanoparticles in Daphnia magna.
TL;DR: 3D tomography confirmed that the QDs appeared to be confined to the gut area of the organism, and there was no evidence of further assimilation into the organism.

Influence of stability on the acute toxicity of CdSe/ZnS nanocrystals to Daphnia magna
TL;DR: Results of the present study suggest that using particle number, instead of mass, as a dose metric for the PEO QDs, produces markedly different conclusions, in that smaller core size does not equate to greater toxicity.
