BIOMOLECULE DETECTION APPARATUS INCLUDING A PLURALITY OF ELECTRODE

摘要

PURPOSE: A biomolecule detecting device having a plurality of electrodes is provided to introduce additional electrodes near to a nanopore, thereby easily guiding particles having electric charges to the nanopore. CONSTITUTION: A biomolecule detecting (100) includes a nanopore element (110), a water tank (101), and a power unit (120). The nanopore element includes a nanopore (111) of a nanosized diameter. The water tank is arranged on the rear surface of the nanopore element. The power unit forms an electric field around the nanopore. The power unit includes a first electrode arranged on the front surface of the nanopore element; a second electrode arranged inside the water tank in the rear side of the nanopore element; and a third electrode arranged around an inlet of the nanopore between the first and second electrodes.
