Quantification of carbon nanotubes in environmental matrices: Current capabilities, case studies, and future improvements

April 6, 2016
Author(s)
Elijah J. Petersen, D. X. Flores-Cervantes, Thomas Bucheli, Lindsay C. Elliott, Jeffrey A. Fagan, Alexander Gogos, Shannon Hanna, Antonio R. Montoro Bustos, Desiree L. Plata, Vytautas Reipa, Paul Westerhoff, Michael R. Winchester, Elisabeth Mansfield
Carbon nanotubes (CNTs) have numerous exciting potential applications approaching commercialization. As such, quantitative measurements of CNTs in key environmental matrices (water, soil, sediment, and biological tissues) are needed to address concerns

The DNA Damaging Potential of Photoactivated P25 Titanium Dioxide Nanoparticles

September 30, 2014

Elijah Petersen, Vytas Reipa, Stephanie S. Watson, Deborah Jacobs, Savelas A. Rabb, Bryant C. Nelson
Titanium dioxide nanoparticles (TiO2 NPs) are found in numerous commercial and personal care products. Thus, it is necessary to understand and characterize their potential environmental health and safety risks. It is well known that photoactivated TiO2 NPs

Probing the intracellular glutathione redox potential using in-cell NMR spectroscopy

Steve Y. Rhieu, Aaron A. Urbas, Daniel W. Bearden, John P. Marino, Vytautas Reipa, Katrice A. Lippa
Non-invasive and real-time analysis of cellular redox processes has been greatly hampered by lack of suitable measurement techniques. Here we describe an in-cell nuclear magnetic resonance (NMR)-based method for measuring the intracellular glutathione

Quantitative measurements of glutathione in yeast cell lysate using 1H NMR

February 20, 2013
Author(s)
Steve Y. Rhieu, Aaron A. Urbas, Katrice Lippa, Vytas Reipa
A method for quantifying the level of glutathione (GSH) in yeast cell lysate is described using 1H NMR analysis. For quantification purposes, the 1H resonances corresponding to the Cys βCH2 of GSH were identified as having the fewest overlapping spectral
