Tunable DNA
July 12, 2016 | Terry Sharrer
DNA can conduct an electrical charge, but as electrons move along a sequence, their pace is faster or slower according to the bases they traverse. Because of this, researchers at Arizona State University report “”We’ve been able to show theoretically and experimentally that we can make DNA tunable by changing the sequence of the “A, T, C, or G” chemical bases, by varying its length, by stacking them in different ways and directions, or by bathing it in different watery environments. . . .” Stacked bases of guanine are the most conductive, suggesting they may be adaptable to making nanowires for medical devices.
