We report fabrication and characterization of a novel real-time, label-free DNA detector, that uses a long nanofluidic channel to stretch a DNA strand and a nanogap detector (with a gap as small as 9 nm) inside the channel to measure the electrical conduction perpendicular to the DNA backbone as it moves through the gap. We have observed electrical signals caused by 1.1 kilobase-pair (kbp) double-stranded (ds)-DNA passing through the gap in the nanogap detectors with a gap equal to or less than 13 nm.
