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 molecular sensor includes a substrate defining a substrate plane, and a plurality of pairs of electrode sheets above or below the substrate at an angle to the substrate plane. The molecular sensor further includes a plurality of inner dielectric sheets between each electrode sheet in each pair of electrode sheets of the plurality of pairs, and an outer dielectric sheet between each pair of electrode sheets of the plurality of pairs.

Abstract: Electronic sensors configured to detect single molecule targets and methods of using and manufacturing such electronic sensors are disclosed. A sensor may include a first electrode and a second electrode separated by a sensor gap. The first and second electrodes can be coupled by a sensor complex that can include a biopolymer bridge molecule and a probe. The probe can interact with a target molecule, and interaction of the probe and target molecule can produce a signal suitable to provide detection of the target molecule.

Abstract: Methods for fabricating at least one nanoparticle include providing one or more substrates and depositing a substance on the one or more substrates. At least one portion of the substance is heated or annealed so the at least one portion beads up on the one or more substrates due to cohesive forces of the substance being greater than adhesive forces between the substrate and the substance. In some methods, a pattern generation process is performed to define the at least one portion. A combination of a substance material for the substance and a substrate material for the one or more substrates may also be selected so that the at least one portion beads up into a predetermined shape. The substance may also be deposited on the one or more substrates with a sub-monolayer thickness or with gaps to further reduce a nanoparticle size.
