  • Abstract
    We report bidirectional conductance modulation in synthetic nanochannels introduced by the translocation of λ-DNA molecules. The translocation signal comprised conductance decrease followed by conductance increase in the same translocation event. The results are consistent with concentration enhancement and depletion effects caused by introduction of asymmetric charge into the nanochannel due to the translocating molecule.
