Abstract: A system for detecting a biomolecule comprises a nano-gap electrode device including a first electrode and a second electrode adjacent to the first electrode. The first electrode can be separated from the second electrode by a nano-gap that is dimensioned to permit the biomolecule to flow through the nano-gap. The nano-gap can have at least a first gap region and a second gap region. The second gap region can be oriented at an angle that is greater than zero degrees with respect to a plane having the first gap region. The system can further include an electrical circuit coupled to the nano-gap electrode device. The electrical circuit can receive electrical signals from the first electrode and the second electrode upon the flow of the biomolecule through the nano-gap.

Abstract: Devices, systems and methods for sequencing protein samples are provided. In some examples, currents generated when a monomer passes through between electrodes of a nanogap electrode pair are measured for each of several different distances, so that monomers are identified when compared to a reference physical quantity of a known monomer, which may be obtained from a current measured with a similar inter-electrode distance(s) at which each of plural kinds of monomers are identifiable and ordered with predetermined accuracy and based on a detected physical quantity obtained from a tunneling current, which may be further normalized by the use of one or more reference substances.

Abstract: The present disclosure provides systems and methods for sequencing nucleic acid molecules using tunneling labels. A sequence of a nucleic acid molecule may be identified with high accuracy using a chip comprising sensors, wherein each individual sensor may comprise at least two electrodes separated by a gap. The electrodes may be configured to generate at least one electrical signal upon binding of a tunneling label associated with a nucleotide. Epigenetic information can also be determined at the same time as a nucleic acid sequence.
