Nanopores incorporating ITO electrodes for electrical gating of DNA at different folding states

Nanopore devices integrated with ITO gate electrodes are fabricated, producing pore diameters G modulates the translocation events. As V G rises from −0.5V to 0.5V, the count of folded-once events increases by ∼5.5X relative to that of unfolded ones, indicating capability of electrically modulating the effective pore cross-section.
