Stable Isotope Tracing – a way forward for Nanotechnology?

Gulson B., Wong H., McCall M., Danon S., Greenoak G., Trotter J., Casey P., Stauber J., Commonwealth Scientifc and Industrial Research Organisation, AU

Numerous publications and reports have expressed health and safety concerns about the production and use of nanoparticles, especially in areas of exposure monitoring, personal use, and environmental fate and transport. We suggest that stable isotopic [...]

Toxicogenomics study of nanomaterials on the model organism zebrafish

Rojo I., Uriarte M., Obieta I., Bustero I., Egizabal A., Pardo M.A., Martínez de Ilárduya O., Azti-Tecnalia, ES

The applications of nanomaterials include fields as biomedicine, cosmetics or food science, raising a concern about the need to determine their toxic effects. Most of the toxicity tests are based on the analysis of classical [...]

An OMICs Approach for Assessing the Safety of Single-Walled Carbon Nanotubes in Human Skin and Lung Cells

Cunningham M.J., Shah M., Lema C., Magnuson S., Falduto M., Balzano L., Resasco D., Houston Advanced Research Center, US

High-throughput OMICs biotechnologies combined with a systems biology approach were used to screen for the toxicity of nanomaterials. Profiling of the macromolecular interactions within human cells was done with mRNA and miRNA expression microarrays (genomics) [...]

Cytotoxicity of Dental Nanocomposite Particles

Kostoryz E.L., Utter C.J., Wang Y., Dusevich V., Spencer P., University of Missouri-Kansas City, US

Safety assessment of dental composites is focused on the toxicity of leachable unreacted monomers. With the advent of nanostructured materials, safety assessment needs to include the potential toxicity of nanoparticles. The objective of this study [...]

Nanotechnologies and Health Maintenance

Rae A., NanoDynamics, US

We have all heard about the marvelous advances being made in the use of nanomaterials in imaging, cancer therapy and controlled release pharmaceuticals. What is less well known is the role of nanotechnology in prevention [...]

Nano-Catalysts and Colloidal Suspensions of Carbo-Iron for Environmental Application

Mackenzie K., Hildebrand H., Kopinke F.-D., Helmholtz Centre for Environmental Research - UFZ, DE

The presentation contains two innovative applications of nano-sized materials for environmental application: 1) Pd catalysts for wastewater treatment. The new ferromagnetic nano-sized Pd catalysts have proved effective for selective dechlorination of industrial wastewater. Extraction by [...]

Aided Transport of Nano-Iron in Clay Soils Using Direct Electric Field

Hannum L., Pamukcu S., Lehigh University, US

The influence of direct current electric fields on the possible electrokinetic delivery of a nano-iron slurry in clay for the purpose of fast and effective remediation of soil contaminants has been tested. Nano-iron can be [...]

Smog Analysis in Urban Areas Using ASTER Data and Its Analysis of Variance with In-Situ Sensors Data

Roy P., Brumfield J.O., Vaseashta A., Graduate program in Physical Sciences, US

This paper describes an approach to assess atmospheric pollutant in the troposphere and their spectral characteristic signatures by using high-spectral and spatial resolution ASTER data and its analysis of variance with in-situ data obtained using [...]

Forensic Environmental Analysis of Nanotechnology Regulation

Scher C.A., Caputo D.L., Quest Consulting, Inc., US

Some considerable effort has recently been displayed by manufacturers, researchers, regulatory bodies, professional organizations, NGOs, and other interested parties addressing how nano-particles and their manufacture should be environmentally regulated. The term environment here is used [...]

An investigation of natural nanoparticles for cleaning applications

Nero M., Tran B., Naturell Clean, Inc., US

Bioremediant cleaning products are investigated for every day use by consumers in their homes. Nano-components such as biosurfactants, enzymes, metaloenzymes, and chelating agents are derived from Sea Kelp and are the result of naturally occurring [...]
