Toxicological effects of functionalized single-walled carbon nanotubes (SWCNTs) on embryonic zebrafish (Danio rerio)

Felix L., Martinez-Rubi Y., Simard B., Goss G., University of Alberta, CA

Since their discovery in 1993, single-walled carbon nanotubes (SWCNTs) have played an integral role in nanotechnology and have been extensively studied due to their unique structural, electrical and mechanical properties. Chemical functionalization and coating of [...]

A safer formulation concept for flame-generated engineered nanomaterials

Gass S., Pyrgiotakis G., Cohen J.M., Sotiriou G.A., Pratsinis S.E., Demokritou P., Harvard School of Public Health, US

Engineering less toxic ENMs that maintain valuable functional properties is crucial to the sustainability of the nanotech industry. Core-shell nanoparticles are particularly interesting in this regard. They exhibit the surface properties of their shells while [...]

The Effect of Photolysis on the Stability and Toxicity of Silver Nanoparticles

Poda A.R., Kennedy A.J., US Army Corps of Engineers, US

The objective of this study was to determine the effect of solar irradiation on the aggregation kinetics and toxicity of a 50 nm silver nanoparticle capped with two different stabilization agents (polyvinylpyrrolidone (PVP) and citrate). [...]

Assessment of release and toxicity of NP from silicon-based polymer composites in a life cycle perspective

Irfan A., Sachse S., Njuguna J., Zhu H., Cranfield University, UK

Nanomaterial integration in public domain raises concerns regarding human health impact. This study examines the possibility of nanoparticle release from new engineered nanocomposites, using real life scenarios in life cycle analysis approach. Physical and biological [...]

Novel Immune Biosensors Based on the Structured Nano-Porous Silicon for Control of Mycotoxins in Environmental Objects

Starodub N.F., Slishek N.F., Pylypenko I.V., Pylypenko L.N., Pylypenko I.V., Pylypenko L.N., National University of Life and Environmental Sciences of Ukraine, UA

To meet all the requirements of practice in respect of high sensitivity of analysis of mycotoxins as well as simplicity, cheapness and rapidity of its currying out we propose to use of structured nano-porous silicon [...]

Tools and Approaches for the Assessment of Nanomaterial Induced Oxidative DNA Damage

Petersen E.J., Marquis B.J., Jaruga P., Dizdaroglu M., Nelson B.C., National Institute of Standards and Technology, US

Determining the effects of various surface coatings on carbon nanotubes (CNTs) is critical given the numerous expected applications of CNTs and their inevitable release into ecosystems. To explore the potential ecotoxicological effects of CNT surface [...]

Multimedia Environmental Distribution of Nanomaterials

Liu H.H., Cohen Y., University of California, Los Angeles, US

In the present study, a generalized model of the multimedia environmental distribution of engineered nanomaterial is developed via multimedia fate and transport modeling to estimate potential exposure levels in various environmental compartments. In this model, [...]
