Evaluation and simulation of silver and copper nanoparticle migration from polyethylene nanocomposites to food and an associated exposure assessment.
193
TL;DR: The potential migration of nanoparticles from PE composite packaging to a food material and the potential for simulation models to accurately capture this migration potential are highlighted; however, variable background levels of copper in the food matrix can make prediction more difficult for trace migration of nanocopper.

TL;DR: Organoclay and zinc oxide nanoparticles (ZnO-NPs) were used for decreasing of the SM migration into food simulants (10 and 50% ethanol) and a used GC-FID method for measuring of the migrated SM showed good precision and accuracy.

TL;DR: The enzymatic browning of the apples slices was reduced for all films during storage, however, the films containing citric acid maintained the color characteristics, reducing the loss of quality associated with the maintenance of acidity, soluble solids, water activity, reduction of polyphenol oxidase and peroxidase activity, thus prolonging the shelf life of the iPhones.

Negligible Particle-Specific Antibacterial Activity of Silver Nanoparticles
TL;DR: This work suggests that AgNP morphological properties known to affect antimicrobial activity are indirect effectors that primarily influence Ag(+) release, and antibacterial activity could be controlled by modulating Ag(+ release, possibly through manipulation of oxygen availability, particle size, shape, and/or type of coating.

TL;DR: The present results suggest that silver nanoparticles do not induce genetic toxicity in male and female rat bone marrow in vivo, and the tissue distribution of silver nanopaticles did show a dose-dependent accumulation of silver content in all the tissues examined.

Metal-based nanoparticles and their toxicity assessment.

TL;DR: There are many challenges to overcome before the authors can determine if the benefits outweigh the risks associated with NPs, and some metal-based NPs are showing increased toxicity, even if the same material is relatively inert in its bulk form.
