Size-dependent effect of zinc oxide on toxicity and inflammatory potential of human monocytes.
TL;DR: Results suggest higher propensity of nano ZnO particles in inducing cytotoxicity and inflammation in human monocytes regardless of micro size, and caution needs to be taken concerning their biological application.

TL;DR: ZnO and SiO2 particles exhibited concentration-dependent toxicity, which was more in their nano size than micron counterpart, however, the toxic response varies depending on type of cell exposed due to differential sensitivity.
Nanosized Zinc Oxide Induces Toxicity in Human Lung Cells
TL;DR: ZnO-NPs cause toxicity in human lung cells possibly through oxidative stress-induced apoptosis, and increased the expression of metallothionein gene, which is considered as a biomarker in metal-induced toxicity.

Carbon Black Particle Exhibits Size Dependent Toxicity in Human Monocytes
TL;DR: Investigations indicate that CB particles in nanosize exhibit higher propensity of inducing cytotoxicity, inflammation, and altered phagocytosis in human monocytes than their micron size.
Silica nanoparticle induces oxidative stress and provokes inflammation in human lung cells
TL;DR: The results indicated that amorphous silica nanoparticle followed hierarchical oxidative stress model and generated oxidative stress which provoked the pro-inflammatory response and caused necrosis in human lung cells.
