Abstract
Devices and methods are presented for electronic sensing of chemical and biochemical analytes. An electronic sensor having a at least two electrodes separated by a nanoscale gap wherein the separation between the first electrode and the second electrode forms a cavity capable of containing a fluid wherein two or more posts comprised of an insulating material extend into the cavity from the face of the first electrode to the face of the second electrode. Optionally, the cavity is closed with a bead. Devices according to embodiments of the invention are capable of detecting chemicals and biochemicals through redox cycling events. Additionally, devices and methods according to embodiments of the invention are adapted to identify and sequence nucleic acid molecules.
