Abstract: In various embodiments a molecular circuit is disclosed. The circuit comprises a negative electrode, a positive electrode spaced apart from the negative electrode, and an enzyme molecule conductively attached to both the positive and negative electrodes to form a circuit having a conduction pathway through the enzyme. In various examples, the enzyme is a polymerase. The circuit may further comprise molecular arms used to wire the enzyme to the electrodes. In various embodiments, the circuit functions as a sensor, wherein electrical signals, such as changes to voltage, current, impedance, conductance, or resistance in the circuit, are measured as substrates interact with the enzyme.

Abstract: A method of analyzing genetic markers includes binding a set of probes to a segment of single stranded nucleic acids. The segment of single stranded nucleic acids includes a repeat region formed of at least two of a repeat unit. The repeat unit can include at least two nucleic acids. The set of probes includes a first probe complementary to the repeat unit. The method can further include directing the segment through a nanopore device and measuring a signal through the nanopore device. The signal can be indicative of the number of repeat units.
