Zinc oxide nanoparticles on silicon
Superlattices and Microstructures, 2006Abstract Self-assembled ZnO nanoparticles are grown by electron beam evaporation of Zn on silicon oxide and silicon substrates and subsequent annealing in oxygen. Characterization by TEM and EELS shows that the nanoparticles can be zinc oxide single crystals grown with their c -axis perpendicular to the substrate; their distribution, size and ...

Interaction of cytochrome c with zinc oxide nanoparticles
Colloids and Surfaces B: Biointerfaces, 2013The influence of pH on the interaction between horse heart ferricytochrome c (cyt c) and zinc oxide nanoparticles (ZnO NPs) has been studied by a small angle scattering as well as UV-vis and FTIR spectroscopy. The observations showed that the optimal pH for the association of protein with nanoparticles is in pH range 5.0-8.0.

Hydrogen sensors based on zinc oxide nanoparticles
2010 IEEE 5th International Conference on Nano/Micro Engineered and Molecular Systems, 2010Pure ZnO, pure MgO and 5 wt%MgO/ZnO nanocomposites were produced by flame spray pyrolysis (FSP) in a single step using zinc naphthenate and magnesium acetate tetrahydrate as Zn and Mg precursors. The particle properties were analyzed by XRD, BET and TEM analyses. The sensing films were prepared by mixing the nanoparticles into an organic paste composed

The toxicology of ion-shedding zinc oxide nanoparticles
Critical Reviews in Toxicology, 2016Zinc oxide nanoparticles (ZnO NPs) are nanomaterials that are widely used in many fields. ZnO NPs are ion-shedding particles, and zinc ions produce important and potent effects that differ from those of other metal or metal oxide NPs. Several studies have reported the toxicological effects of ZnO NPs administered via several different routes, including
