Fig. 1From: Protein corona: implications for nanoparticle interactions with pulmonary cellsTransmission electron micrographs (TEM) of nanoparticle suspensions in DI water. a CeO2. b Si-CeO2. Nanothin coatings of amorphous silica are shown (arrows). A higher magnification of additional Si-CeO2 NPs are shown in the inset. The silica coating appears as less electron dense coating (arrowheads) surrounding the core CeO2 NPs. c BaSO4. d ZnO nanorodsBack to article page
