TL;DR: Toxicity and dustiness data can be used to compare different MWCNT materials and to select the material with the lowest risk potential for a given application, but nonetheless strict industrial hygiene measures must be taken during handling and processing.

TL;DR: Tissue distribution and toxicity of intravenously administered nanoparticles of titanium dioxide (TiO2) showed expected tissue distribution, no obvious toxic health effects, no immune response, and no change in organ function indicate that TiO2 nanoparticles could be used safely in low doses.

TL;DR: Enhanced understanding of biophysical properties and cellular effects results in improved testing strategies and enables the selection and production of safe materials, and suggests that hazard potential is not determined by a single physico-chemical property but instead depends on a combination of material properties.

TL;DR: In this pioneering and preliminary evaluation, the hazards cannot be distinguished with or without nanofiller, and in-vivo instillation in rats is used to quantify physiological effects on degradation products from abraded nanocomposites.

TL;DR: In most studies with topical skin application, unintentional permeation and systemic availability were not observed; permeation for some NM with distinct properties was observed in animals and upon inhalation, low levels of primary model nanoparticles became systemically available.
