3. Gold nanorod separation and characterization by asymmetric-flow field flow fractionation with UV-Vis detection
Topic: Nanotech/Environment, Health & Safety
Published: 11/14/2012
Authors: Julien Claude Maurice Gigault, Tae Joon Cho, Robert I MacCuspie, Vincent A Hackley
Abstract: The application of asymmetrical-flow field flow fractionation (A4F) for gold nanorod (GNR) fractionation and characterization was comprehensively investigated. We report on two novel aspects of this application. The first addresses the analytical cha ...

4. Quantifying Dithiothreitol Displacement of Functional Ligands from Gold Nanoparticles
Topic: Nanotech/Environment, Health & Safety
Published: 10/27/2012
Authors: De-Hao Tsai, Frank W DelRio, Sherrie R. Elzey, Suvajyoti S. Guha, Michael Russel Zachariah, Vincent A Hackley, Melanie P Shelton
Abstract: Dithiothreitol (DTT)-based displacement is widely utilized for separating ligands from their gold nanoparticle (AuNP) conjugates, a critical step for differentiating and quantifying surface-bound functional ligands and therefore the effective surface ...

5. Disentangling the effects of polymer coatings on silver nanoparticle agglomeration, dissolution, and toxicity to determine mechanisms of nanotoxicity
Topic: Nanotech/Environment, Health & Safety
Published: 9/1/2012
Authors: Justin M Zook, Melissa Danielle Halter, Danielle Cleveland, Stephen E Long
Abstract: Silver nanoparticles (AgNPs) are frequently coated by a variety of polymers, which may affect various intertwined mechanisms of toxicity, including agglomeration and dissolution rate. Here, we measure how citrate, dextran, poly(ethylene glycol) (PEG ...

6. Tumor Necrosis Factor Interaction with Gold Nanoparticles
Topic: Nanotech/Environment, Health & Safety
Published: 3/14/2012
Authors: De-Hao Tsai, Sherrie R. Elzey, Frank W DelRio, Robert I MacCuspie, Suvajyoti S. Guha, Michael Russel Zachariah, Athena M Keene, Jeffrey D Clogston, Vincent A Hackley
Abstract: We report on a systematic investigation of molecular conjugation of tumor necrosis factor protein-α (TNF) onto gold nanoparticles (AuNPs) and the subsequent binding behavior to its antibody (anti-TNF). We employ a combination of physical and spe ...

7. Pilot Estuarine Mesocosm Study on the Environmental Fate of Silver Nanomaterials Leached from Consumer Products
Topic: Nanotech/Environment, Health & Safety
Published: 1/10/2012
Authors: Danielle Cleveland, Stephen E Long, Paul L. Pennington, Emily Cooper, Michael H. Fulton, Geoffrey I. Scott, Elijah J Petersen, Timothy M Brewer, Jeffrey M Davis, Laura J Wood
Abstract: Although nanosilver consumer products (CPs) now enjoy widespread availability, little work has been done to determine the environmental fate and leaching of silver nanoparticles (AgNPs) from these products. This type of work is crucial, since the lif ...

8. Predictive Gold Nanocluster Formation Controlled by Metal-Ligand Complexes
Topic: Nanotech/Environment, Health & Safety
Published: 1/9/2012
Authors: John M. Pettibone, Jeffrey W Hudgens
Abstract: The formation of ligand-protected transition metal nanoclusters in size-selective syntheses is driven by the inherent properties of the protecting ligands. We have previously reported the selective, monodisperse product formation of phosphine protect ...

10. Measuring agglomerate size distribution and dependence of localized surface plasmon resonance absorbance on gold nanoparticle agglomerate size using analytical ultracentrifugation
Topic: Nanotech/Environment, Health & Safety
Published: 9/3/2011
Authors: Justin M Zook, Vinayak Rastogi, Robert I MacCuspie, Athena M Keene, Jeffrey A Fagan
Abstract: Nanoparticles frequently agglomerate when dispersed into relevant biological and environmental media, with the resulting change to the effective size distribution dramatically affecting the potential nanotoxicity and the absorbance for biosensor ...
