Abstract
Embodiments of the disclosure are directed to a device for molecule sensing. In some embodiments, the device includes a first electrode separated from a second electrode by a dielectric layer. The first electrode comprises a large area electrode and the second electrode comprises a small area electrode. At least one opening (e.g., trench) cut or otherwise created into the dielectric layer exposes a tunnel junction therebetween whereby target molecules in solution can bind across the tunnel junction.

1-39. (canceled)
A device for detecting one or more target molecules comprising:
- a first electrode having a first thickness;
- a dielectric layer covering the first electrode;
- a second electrode having a second thickness, the second electrode being separated from the first electrode by the dielectric layer, wherein the surface area of the second electrode is less than the surface area of the first electrode;
- and
- at least one trench cut or etched through at least the second electrode and dielectric layer and configured to expose a junction between the electrodes to facilitate connection of one or more target molecules with the first and second electrodes.
