Aggregation and Fate of Fullerene Nanoparticles in Aquatic Environments

Chen K.L., Elimelech M., Yale University, US

Fullerene has unique chemical properties and physical structure, and is emerging in a wide range of electronics and biomedical applications. However, toxicity studies have raised concern that fullerene may have adverse human health effects. With [...]

Multi-scale, Mechano-biological Model of Nanoparticle Toxicity

Jenkins J., Pant K., Hood J., Sundaram S., CFD Research Corporation, US

Multiscale simulation of the toxic physiological effects of short and long term exposure to nanoparticles (NP) requires a unified quantitative understanding of NP deposition, partitioning of NP within the body (lung, liver, spleen, and brain), [...]

Testing and Evaluation of Nanoparticle Efficacy on E. Coli, and Bacillus Anthracis Spores

Sloan M., Farnsworth S., Nanotechnologies, Inc., US

Nanoparticles of metals, including silver, when dispersed in wayer were shown to have efficacy against e. coli and bacillus anthracis.

New Guidelines for Selecting Best Extraction Methods of EPS Using Atomic Force Microscopy

Kang S., Ahn Y., Choi H., Elimelech M., Yale University, US

In this study, we applied AFM to develop the guideline during the selection of best extraction methods for exocellular polymeric substances (EPS). A single cell of S. cerevisiae was glued at the end of the [...]

Growth and Some Enzymatic Responses of E. coli to Photocatalytic TiO2

Erdem A., Metzler D., Chou H.W., Lin H-Y, Huang C.P., University of Delaware, US

The effects of photocatalytic nano-TiO2 on the survival or die-off of E. coli (e.g. TK2) were investigated under ambient conditions. Experimentally, a 28-h E. coli culture was exposed to photocatalytic nano-TiO2 at various concentrations, e.g., [...]

“Cultural Bonds” in High Technology: Collaborations between Chinese Researchers in Nanotechnology

Leung R., Li J., University of Wisconsin-Madison, US

Socio-cultural issues have attracted increasing attention from policy makers in high technology. For example, a certain “culture” of high-tech fear, exemplified by Michael Crichton’s best-selling novel Prey, seems to have emerged in U.S. In this [...]
