Inductively Expandable Supraparticles as Microscopic Force Generators for Remote Mechanical Actuation

Advanced Materials, EarlyView.
This study demonstrates the combination of magnetic nanoparticles and functional blowing agents into supraparticles. Upon induction heating, they actuate via rapid gas generation or extensive volume expansion. These supraparticles lift up to 25 000 times their own mass and rapidly open cured epoxy resins, providing a versatile strategy for fast micron ...

Genotoxicity and DNA Repair Processes of Zinc Oxide Nanoparticles

Journal of Toxicology and Environmental Health, Part A, 2014
Two different sizes of zinc oxide nanoparticles (ZnO NP, ≤ 35 nm and 50-80 nm) were tested in the human lymphoblastoid cell line TK6 to increase our knowledge on their genotoxic potential. The comet assay was the system used, and the results obtained showed that the highest concentration tested (100 μg/ml) for the two selected compounds was genotoxic ...

Synthesis, characterization and photocatalytic activities of Ag-N-codoped ZnO nanoparticles for degradation of methyl red

Bulletin of the Chemical Society of Ethiopia, 2013
Ag-N-codoped zinc oxide nanoparticles were synthesized by a one-step impregnation of Ag in N-doped ZnO nanoparticles. The morphologies and structures of the as-synthesized nanomaterials were investigated by using X-ray diffraction (XRD), transmission ...

Zinc Oxide Nanoparticles: The Hidden Danger [PDF]

International Journal of Biochemistry, Biophysics & Molecular Biology, 2017
Zinc oxide nanoparticles (ZnO-NPs) are used in many industries and medications, increasing the exposure to ZnO-NPs that may have harmful side effects. So, we studied the hepatotoxic effect of ZnO-NPs and explored the role of vitamin E in the reduction of their toxic effects.
