Bioavailability of silver nanoparticles and ions: from a chemical and biochemical perspective
Renata Behra,Laura Sigg,Martin J. D. Clift,Fabian Herzog,Matteo Minghetti,Blair D Johnston,Alke Petri-Fink,Barbara Rothen-Rutishauser,Barbara Rothen-Rutishauser +8 more
TL;DR: The aim of this review is to provide a comprehensive, interdisciplinary overview—for biologists, chemists, toxicologists as well as physicists—regarding the production of silver NPs, its chemical and biochemical behaviours towards/within a multitude of relative and realistic biological environments and also how such interactions may be correlated across a plethora of different biological organisms.

Modeling flows and concentrations of nine engineered nanomaterials in the Danish environment.
TL;DR: This work provides material flow data and environmental concentrations of nine ENM in Denmark and is the first study that distinguishes between photostable TiO2 and photocatalyticTiO2, and provides first exposure estimates for quantum dots, carbon black and CuCO3.

Size-dependent acute toxicity of silver nanoparticles in mice.
TL;DR: Results suggested that smaller AgNPs, e.g., those measuring 10 nm in diameter, had higher acute toxicity in mice, and were associated with higher histopathological changes.
In vitro and in vivo genotoxicity investigations of differently sized amorphous SiO2 nanomaterials.
Elena Maser,Markus Schulz,Ursula G. Sauer,Martin Wiemann,Lan Ma-Hock,Wendel Wohlleben,Andrea Hartwig,Robert Landsiedel +7 more
TL;DR: The study shows that colloidal amorphous SiO2 with different particle sizes may induce genotoxic effects in lung cells in vitro at comparatively high concentrations, even though pronounced pulmonary inflammation evolved in the rat lung.

Mimicking exposures to acute and lifetime concentrations of inhaled silver nanoparticles by two different in vitro approaches.
Fabian Herzog,Kateryna Loza,Sandor Balog,Martin J. D. Clift,Matthias Epple,Peter Gehr,Alke Petri-Fink,Barbara Rothen-Rutishauser +7 more
TL;DR: It has been shown that the ALI as well as the suspension conditions for the lower concentrations after 4 h, reflecting real-life concentrations of an acute 24 h exposure, did not induce any adverse effects in a complex 3D model mimicking the human alveolar/airway barrier.

Comparison of the mechanism of toxicity of zinc oxide and cerium oxide nanoparticles based on dissolution and oxidative stress properties.

TL;DR: The results demonstrate that metal oxide nanoparticles induce a range of biological responses that vary from cytotoxic to cytoprotective and can only be properly understood by using a tiered test strategy such as that developed for oxidative stress and adapted to study other aspects of nanoparticle toxicity.
Exposure modeling of engineered nanoparticles in the environment.

TL;DR: The results of this study make it possible for the first time to carry out a quantitative risk assessment of nanoparticles in the environment and suggest further detailed studies of nano-TiO2.

Nanoparticle Silver Released into Water from Commercially Available Sock Fabrics
Troy M. Benn,Paul Westerhoff +1 more
TL;DR: Variable leaching rates among sock types suggests that the sock manufacturing process may control the release of silver, and physical separation and ion selective electrode (ISE) analyses suggest that both colloidal and ionic silver leach from the socks.
