Abstract
An apparatus is provided for sensing a molecule in a sample. The apparatus utilizes an electric field to draw molecules from a first chamber through an aperture, defined by a chemical layer, into a second chamber. The apparatus can detect a DNA molecule with, for example, 4, 5, or 6 unique base pairs. As molecules pass through the aperture, a sensor detects or measures a change in an electric parameter used to generate the electric field, thereafter translating the change in the electric parameter into information about the molecule. A divider element separates the first and second chambers and supports a chemical layer defining the aperture. The apparatus enables detection or measurement of molecules over prolonged time at a higher electric field strength than other nanopores, due to a combination of the shape of the divider, structural elements thereon, and thickness of the chemical layer at the aperture.
