Abstract: This invention is based, in part, on our discovery of an essentially one-step, label-free system comprising a sensing unit having a redox current reporter and a nucleic acid sequence complementary to that of a target nucleic acid of interest or sufficiently complementary to that of the target nucleic acid or a sequence therein to specifically bind the target nucleic acid. The sensing unit is bound to an electroconductive substrate (e.g., a carbon- or metal-containing microelectrode (e.g., a gold microelectrode)), and the system includes a signal amplification mechanism that does not rely upon a redox enzyme and thereby overcomes a fundamental limitation of microelectrode DNA sensors that fail to generate detectable current in the presence of only small amounts of a target nucleic acid.
