In vitro Model for Identifying Subchronic Carbon Nanotube Exposure and Lung Cancer Gene Markers

Stueckle T., Davidson D., Derk R., Meighan T., Castranova V., Rojanasakul Y., Wang L., National Institute for Occupational Safety and Health, US

Concern for increased risk of carbon nanotube-associated lung disease, including carcinogenesis, has been raised due to asbestos-like characteristics. To date, no particle specific nanomaterial exposure or lung cancer markers have been identified. Here, we use [...]

Outwitting the uncertainty of nanotechnology risks through environmental life cycle assessment

Steevens J., Chappell M., Janzen D., Edwards D., Shih W., US Army Engineer Research and Development Center, US

The goal of this study was to evaluate a carbon nanotube (CNT) product in terms of life cycle phases representing points where resources are expended and emissions are created. The study described here is important [...]

Dispersion of Carbon Nanotubes with Organic Dyes

Zhang W., Wu C., Zhang W., Dalian University of Technology, CN

Owing to the presence of van der Waals’ forces, carbon nanotubes (CNTs) have the propensity to aggregate together and form bundles, which considerably hinders their applications. In this paper, organic dyes were used to suspend [...]

3-D characterization of carbon nanotube-polymer composites using scanning electron microscopy and confocal Raman microscopy

Zhao M.H., Cannara R.J., National Institute of Standards and Technology, US

3D characterization of the dispersion of CNTs in a polymer matrix is a critical step toward understanding and improving the performance of CNT polymer composites. In this study, SEM and confocal Raman microscopy (CRM) were [...]

Structure and Electrical Properties of Polypropylene-Graphite-Carbon black/ Nanotubes Hybrid Conducting Composites

Ramanujam B.T.S., Mehta H., Khare A., Radhakrishnan S., Maharashtra Institute of Technology, IN

Low cost conducting composites are required for bipolar plates of fel cells and battery electrodes. Polypropylene filled with graphite has been tried in the past but acceptable level of conductivity is reached only at high [...]

Metastatic diagnosis of colon cancer by vertically aligned carbon nanotube based electromechanical biosensor

Abdolahad M., Taghinejad H., Taghinejad M., Taghinejad H., Taghinejad M., Janmaleki M., Mohajerzadeh S., University of Tehran, IR

vertically aligned carbon nanotube based electrical biosensor was demonstrated as a more rapid, sensitive and specific device for metastatic diagnosis of colon cancer cells based on the mechanical entrapment of metastatic cancer cells on vertically [...]

Carbon nanotubes-metal nanoparticle heterostructures embedded within stimuli-responsive hydrogel for controlled delivery applications

Shi W., Venkatanarayanan A., Chopra N., The University of Alabama, US

In this work we report a novel hybrid hydrogel by embedded complex carbon nanotube-metal nanoparticle architectures within a hydrogel network. This leads to a novel triggering mechanism for release of multiple chemical species at controlled [...]

Mechanism and Free Energy of DNA Hybridization on Single-Walled Carbon Nanotubes Using Adaptive Biasing Force Simulations

Chien M.W., Johnson Jr. A.T.C., Johnson R.R., Pillai S., Singh S.R., Johnson Jr. A.T.C., Johnson R.R., University of Pennsylvania, US

DNA-carbon nanotube hybrids (DNA-NT) consist of single stranded DNA self-assembled to the sidewall of single-walled carbon nanotubes. DNA-NT show great promise for applications in nanotechnology, including chemical sensing and sequence-specific DNA detection. Details of the [...]
