N2 - Nanoparticles can acquire a biomolecular corona with a species-specific biological identity. However, "non-self" incompatibility of recipient biological systems is often not considered, for example, when rodents are used as a model organism for preclinical studies of biomolecule-inspired nanomedicines. Using zebrafish embryos as an emerging model for nano-bioimaging, here we unravel the in vivo fate of intravenously injected 70 nm SiO2 nanoparticles with a protein corona pre-formed from fetal bovine serum (FBS), representing a non-self biological identity. Strikingly rapid sequestration and endolysosomal acidification of nanoparticles with the pre-formed FBS corona were observed in scavenger endothelial cells within minutes after injection.
