Toxic Potential of Materials at the Nanolevel
TLDR
The establishment of principles and test procedures to ensure safe manufacture and use of nanomaterials in the marketplace is urgently required and achievable.
View on Publisher
Understanding biophysicochemical interactions at the nano-bio interface.
TLDR
Probing the various interfaces of nanoparticle/biological interfaces allows the development of predictive relationships between structure and activity that are determined by nanomaterial properties such as size, shape, surface chemistry, roughness and surface coatings.

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

Comparison of the abilities of ambient and manufactured nanoparticles to induce cellular toxicity according to an oxidative stress paradigm.
TLDR
It is demonstrated that ROS generation and oxidative stress are a valid test paradigm to compare NP toxicity, and particle interactions with cellular components are capable of generating oxidative stress.

Use of metal oxide nanoparticle band gap to develop a predictive paradigm for oxidative stress and acute pulmonary inflammation.
TLDR
It is demonstrated that it is possible to predict the toxicity of a large series of MOx nanoparticles in the lung premised on semiconductor properties and an integrated in vitro/in vivo hazard ranking model premisedon oxidative stress.

The role of oxidative stress in ambient particulate matter-induced lung diseases and its implications in the toxicity of engineered nanoparticles.

Cationic polystyrene nanosphere toxicity depends on cell-specific endocytic and mitochondrial injury pathways.
TLDR
The results of this study demonstrate the importance of cell-specific uptake mechanisms and pathways that could lead to sensitivity or resistance to cationic particle toxicity.

Quinones and Aromatic Chemical Compounds in Particulate Matter Induce Mitochondrial Dysfunction: Implications for Ultrafine Particle Toxicity
TLDR
It is shown that aliphatic, aromatic, and polar organic compounds, fractionated from diesel exhaust particles (DEPs), exert differential toxic effects in RAW 2647 cells, suggesting that DEP and UFP effects on the PTP and ΔΨm are mediated by adsorbed chemicals rather than the particles themselves.

Processing pathway dependence of amorphous silica nanoparticle toxicity: colloidal vs pyrolytic.
TLDR
This study emphasizes that not all amorphous silicas are created equal and that the unusual toxicity of fumed silica compared to that of colloidal silica derives from its framework and surface chemistry along with its fused chainlike morphology established by high-temperature synthesis and rapid thermal quenching.

Decreased dissolution of ZnO by iron doping yields nanoparticles with reduced toxicity in the rodent lung and zebrafish embryos.
TLDR
Data show that Fe doping is a possible safe design strategy for preventing ZnO toxicity in animals and the environment.
