Elijah J. Petersen, Roger A. Pinto, Liwen Zheng, Qingguo Huang, Peter E. Landrum, Walter J. Weber
Carbon nanotubes (CNTs) are often modified for their different intended application potentials to enhance their aqueous stability or change properties such as their surface charge. Such changes may also profoundly impact their environmental behaviors. We

Influence of Polyethyleneimine Graftings of Multi-Walled Carbon Nanotubes on Their Accumulation and Elimination by and Toxicity to Daphnia magna

December 23, 2010

Elijah J. Petersen, Roger A. Pinto, Danielle J. Mai, Peter E. Landrum, Walter J. Weber
Carbon nanotubes (CNTs) are often modified for different intended applications which often changes the nanotubes’ physicochemical properties, such as surface charge. Assessing the extent to which such modifications to carbon nanotubes influence their

Mechanisms and Measurement of Nanomaterial-Induced Oxidative Damage to DNA

June 22, 2010
Author(s)
Bryant C. Nelson, Elijah J. Petersen
Many of the current investigations on the environmental health and human safety risks of engineered nanomaterials focus on their short-term acute effects. However, the long-term chronic effects of nanomaterials on living systems, and in particular, on the
