Metal dioxide nanoparticles (NPs) are produced in ever-increasing amounts and widely used in industrial, medical and consumer products. They may pose potential risks to the environment. In this study we quantitatively evaluated the phytoavailability of CeO2NPs, ZrO2NPs and SiO2NPs to wheat (Triticum aestivum L.).

Toxicity of silver nanoparticles—Nanoparticle or silver ion?
Toxicology Letters, 2012The toxicity of silver nanoparticles (AgNPs) has been shown in many publications. Here we investigated to which degree the silver ion fraction of AgNP suspensions, contribute to the toxicity of AgNPs in A549 lung cells. Cell viability assays revealed that AgNP suspensions were more toxic when the initial silver ion fraction was higher.

Nanoparticles and the Environment
Journal of the Air & Waste Management Association, 2005Nanoparticles are a class of materials with properties distinctively different from their bulk and molecular counterparts. A critical review of the very broad topic of environmental nanoparticles is presented. Because of the vast nature of the topic, the review is focused primarily on gas-borne nanoparticles.

Wetting of nanoparticles and nanoparticle arrays
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2002Abstract We report investigations of nanoparticulate wetting carried out using molecular dynamics simulations. Despite their small size, model ‘Lennard–Jones’ nanoparticles in simple Lennard–Jones solvents exhibit well defined contact angles, which for high surface tension interfaces have been shown to obey Young's equation with surprising accuracy ...

Toxicity of CeO2 nanoparticles – The effect of nanoparticle properties
Journal of Photochemistry and Photobiology B: Biology, 2015Conflicting reports on the toxicity of CeO2 nanomaterials have been published in recent years, with some studies finding CeO2 nanoparticles to be toxic, while others found it to have protective effects against oxidative stress. To investigate the possible reasons for this, we have performed a comprehensive study on the physical and chemical properties ...
