Bacterial response to oxidation studied as toxin barometer

is focused on neuroscience, particularly brain injury and aging, and nanotechnology (http://nanoneuro.vcom.vt.edu/).

It is a good sensor because it measures biological effect rather than concentrations, Rzigalinski said. So we can measure oxidative damage when we stick the sensor in the water, not individual concentrations of individual chemicals. It also announces the presence of an oxidative toxin you havent identified.

We dont have to have 20 sensors for 20 toxins. We can sense the presence of any oxidative toxin, Love said.

Ikuma, who was an undergraduate biology student at Virginia Tech when she began working with Love, has now come full circle from a biology student working on a civil engineering research project to an engineering student working on a biology project. She will deliver the paper, Predicting the public health impact of oxidative toxins using a bacterial glutathione-gated potassium efflux stress response biosensor (GEOC 51) at 3:25 p.m., Monday, March 26, in McCormick Place North room N427A. Rzigalinski and Nancy Love are the co-authors.
