| additional information | design of a E-DNA sensor such that, in the presence of target DNA, the electrode self-assembled signaling probe hybridizes with the target DNA to form a duplex in the form of a 3'-blunt end at signaling probe and a 3'-overhang end at target DNA. In this way, Exo III specifically recognizes this structure and selectively digests the signaling probe. As a result, the target DNA dissociates from the duplex and recycles to hybridize with a new signaling probe, leading to the digestion of a large amount of signaling probes gradually, method development and mechanism, overview. The E-DNA sensor has an excellent differentiation ability for single mismatches with fairly good stability | Escherichia coli | ? | - |
