  • Patent number: 11391719
    Abstract: Devices for sequencing linear biomolecules (e.g., DNA, RNA, polypeptides, proteins, and the like) using quantum tunneling effects, and methods of making and using such devices, are provided. A nanofabricated device can include a small gap formed by depositing a thin film between two electrodes, and subsequently removing the film using an etching process. The width of the resulting gap can correspond with the size of a linear biomolecule such that when a part of the biomolecule (e.g., a nucleobase or amino acid) is present in the gap, a change in tunneling current, voltage, or impedance can be measured and the part of the biomolecule identified. The gap dimensions can be precisely controlled at the atomic-scale by, for example, atomic layer deposition (ALD) of the sacrificial film. The device can be made using existing integrated circuit fabrication equipment and facilities, and multiple devices can be formed on a single chip.
