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.

Human exposure assessment of silver and copper migrating from an antimicrobial nanocoated packaging material into an acidic food simulant
Joseph Christopher Hannon,Joseph P. Kerry,Malco C. Cruz-Romero,Shafrina Azlin-Hasim,Shafrina Azlin-Hasim,Michael A. Morris,Michael A. Morris,Enda Cummins +7 more
TL;DR: The predicted human exposure to Ag and Cu was used to calculate a margin of exposure (MOE) for ionic species ofAg and Cu, which indicated the safe use of the food packaging in a hypothetical scenario (e.g. as fruit juice packaging).

Nanomaterials in food contact materials; considerations for risk assessment
K Cwiek-Ludwicka,Jan K Ludwicki +1 more
TL;DR: The article underlines the need to develop predictive and validated toxicological tests that can be used to screen for potential hazards, and also to develop new methodology for measuring nanoparticles in biological matrices to assess human exposure.
Migration of copper from nanocopper/polypropylene composite films and its functional property
TL;DR: Wang et al. as mentioned in this paper showed that nanocopper particles were physically dispersed in homopolymer polypropylene (PP-H) matrix and the addition of nanocoppers could significantly improve thermal and mechanical properties of composite films, ensuring its potential utilization for food packaging.

A systematic review on the effects of nanomaterials on gut microbiota
TL;DR: In this paper , a systematic assessment of the effects of nanomaterials (NMs) on GM dysbiosis is presented. But, the authors do not discuss the differences on the reported effects of NM by type and sex of organisms, size, shape and surface properties of NMs as well as effects of exposure to mixtures of NM.

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.

Rapid generation of protein aerosols and nanoparticles via SAW atomisation
TL;DR: In this article, a surface acoustic wave (SAW) atomizer was used to generate monodisperse aerosols and particles for drug delivery applications, including insulin liquid aerosols for pulmonary delivery and solid protein nanoparticles.

Toxicity of silver nanoparticles in zebrafish models.
TL;DR: The results suggest that silver nanoparticles induce a dose-dependent toxicity in embryos, which hinders normal development.

Twenty-Eight-Day Oral Toxicity, Genotoxicity, and Gender-Related Tissue Distribution of Silver Nanoparticles in Sprague-Dawley Rats
Yong Soon Kim,Jin Sik Kim,Hyun Sun Cho,Dae Sik Rha,Jae Min Kim,Jung Duck Park,Byung-Sun Choi,Ruth Lim,Hee Kyung Chang,Yong Hyun Chung,Il Hoon Kwon,Jayoung Jeong,Beom Seok Han,Il Je Yu +13 more
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.
