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

May 13, 2013
Author(s)
Elijah J. Petersen, Bryce Marquis, Pawel Jaruga, M Miral Dizdar, Bryant C. Nelson
Hyphenated mass spectrometry techniques have been employed as one of the primary analytical tools for investigating the effects of ionizing radiation, chemical/biological carcinogens, and oxygen derived free radicals on the induction and subsequent repair

NIST Gold Nanoparticle Reference Materials Do Not Induce Oxidative DNA Damage

February 1, 2013
Author(s)
Bryant C. Nelson, Donald H. Atha, John T. Elliott, Bryce J. Marquis, Elijah J. Petersen, Danielle Cleveland, Stephanie S. Watson, I-Hsiang Tseng, Andrew Dillon, Melissa Theodore, Joany Jackman
Well-characterized, nanoparticle reference materials are urgently needed for nanomaterial toxicity studies. The National Institute of Standards and Technology has developed three gold nanoparticle (AuNP) reference materials (10 nm, 30 nm, 60 nm) to address

Impact of Size on Carbon Nanotube Transport in Natural Porous Media

September 17, 2012
Author(s)
Denis O'Carroll, Xeuying Liu, Nikolai Mattison, Elijah Petersen
Carbon nanotubes are the subject of intense research due to their unique properties: light weight, significant strength, excellent conductivity, and outstanding chemical resistance. This has led to their application in a wide variety of industries, (e.g

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

Hyphenated mass spectrometry techniques have been employed as one of the primary analytical tools for investigating the effects of ionizing radiation, chemical/biological carcinogens, and oxygen derived free radicals on the induction and subsequent repair

Interactions of 14C-labeled multi-walled carbo nanotubes with soil minerals in water

March 2, 2012
Author(s)
Liwen Zhang, Elijah Petersen, Wen Zhang, Yongsheng Chen, Miguel Cabrera, Qingguo Huang
One of the critical factors related to the environmental fate of carbon nanotubes (CNTs) is their phase distribution between soil or sediment and water. To quantitatively understand the interaction between the model soil components and multiwalled carbon

Pilot Estuarine Mesocosm Study on the Environmental Fate of Silver Nanomaterials Leached from Consumer Products

January 10, 2012
Author(s)
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
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 lifecycle

Copper oxide nanoparticle mediated DNA damage in terrestrial plant models

December 22, 2011
Author(s)
Bryant C. Nelson, Donald H. Atha, Elijah J. Petersen, Huanhua Wang, Danielle Cleveland, Richard D. Holbrook, Pawel Jaruga, M Miral Dizdar, Baoshan Xing
Engineered nanoparticles, due to their unique electrical, mechanical and catalytic properties, are presently found in many commercial products and will be intentionally or inadvertently released at increasing concentrations into the natural environment
