Abstract: The present disclosure provides methods and systems for detecting or analyzing a biomolecule. The methods and systems may comprise the use of a plurality of electrodes and a solution which may comprise a variety of reagents. In an example, the solution may comprise one or more redox-active molecules or compounds which may undergo or facilitate a redox cycling process. The redox cycling process may generate an electric signal that may be measured by one or more of the plurality of electrodes. An introduction of a nucleotide having a redox cycling current modifying particle coupled thereto to the solution may result in a change in the electric signal. The change in the electric signal may be used to identify the biomolecule or a portion thereof.

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.
