TL;DR: In this paper , the authors describe the outcome of a large international interlaboratory study of the measurement of particle number concentration of colloidal nanoparticles, project 10 of the technical working area 34, "Nanoparticle Populations" of the Versailles Project on Advanced Materials and Standards (VAMAS).
Effect of an isoxsuprine-resin preparation on blood flow in the equine thoracic limb
TL;DR: Receptor binding studies demonstrated strong alpha-receptor binding, and this binding was so strong that even at isoxsuprine concentrations below the detection level receptors could have been stimulated.

TL;DR: In this article , a comparison of the performance of different microscopy-based techniques applied to complexly shaped nanoparticles is presented, showing good consistency of the measured size by different techniques in cases where special care was taken for sample preparation, instrument calibration, and the clear definition of the measurand.
Traceable characterization of hollow organosilica beads as potential reference materials for extracellular vesicle measurements with optical techniques.

TL;DR: Hollow organosilica beads (HOBs) are promising RM candidates for concentration measurements of EVs based on light scattering, as the shape, low refractive index, and number concentration of HOBs are comparable to EVs of the respective size range that can be detected with current optical instrumentation.
