University of Texas chemist receives major grant to improve detection of drug-resistant tuberculosis
Date:12/22/2011

case the signal it will amplify will be the presence of the TB bacteria in saliva.

Ellington says the ultimate goal of such "molecular computation" is to develop a DNA circuit that recognizes drug-resistant TB bacteria and produces a color easily seen by the naked eye. Appropriate interventions can then be made quickly for the patient and before the TB spreads further.

"From our research and that of others, we know what all the parts are that will make this work," Ellington said. "The problem we are working on now is making the circuit sensitive enough to the minute levels of TB bacteria in a normal sample and decreasing false positives."
