  • Patent number: 8003374
    Abstract: A reagentless, reusable bioelectronic DNA, or other oligonucleotide sequence sensor is disclosed. The sensor includes an oligonucleotide (aptamer) probe tagged with a electroactive, redoxable moiety, self-assembled on or near an electrode. This surface-confined oligonucleotide (aptamer) probe structure undergoes hybridization-induced conformational change in the presence of the target which changes the electron-transfer distance between the redoxable moiety and the electrode thereby providing a detectable signal change. In an alternative embodiment, the target can harbor the redoxable moiety.

  • Publication number: 20040191801
    Abstract: A reagentless, reusable bioelectronic DNA or RNA sequence sensor is disclosed. The sensor includes a DNA probe tagged with a electroactive, redoxable moiety, self-assembled on or near an electrode. This surface-confined DNA probe structure undergoes hybridization-induced conformational change in the presence of the target DNA/RNA sequence which change the electron-transfer distance between the redoxable moiety and the electrode thereby providing a detectable signal change. In a preferred application, the target sequence is associated with an object and its detection is correlated with the authenticity of the object.
