A device for characterization of polymers is described. The device includes a plurality of atomically thin electrodes with their edges exposed along a fluidic channel through which a single stranded polymer molecule is controllably positioned. The polymer includes a series of subunits where each in sequence is identified by an electrical signal between two of the electrodes when in contact with the two electrodes. The position of the polymer strand within the fluidic channel is controlled by voltages applied to the atomically thin electrodes as well as global electrodes located within the fluidic channel. The electrical signal includes tunneling currents along the length of each segment, ionic currents within solutions containing the polymer segments, and, in some embodiments tunneling currents across each polymer segment, and, based upon those measurements, identifying the chemical composition of each segment and therefore the chemical composition of the polymer as a sequence of subunits.
