Zebrafish embryos help prove what happens to nanoparticles in the blood

Fluorescently labelled 70 nm SiO2 nanoparticles were injected into the bloodstream of 3 days old transgenic zebrafish embryos and live-imaged at 3 min after the injection. The insets show schematics for the two conditions tested: ....
