Ionic Coulomb Blockade in Nanopores
Matt Krems, Massimiliano Di Ventra
Understanding the dynamics of ions in nanopores is essential for applications ranging from single-molecule detection to DNA sequencing. We show both analytically and by means of mo…
Quantized ionic conductance in nanopores
Michael Zwolak, Johan Lagerqvist, Massimiliano Di Ventra
Ionic transport in nanopores is a fundamentally and technologically important problem in view of its occurrence in biological processes and its impact on novel DNA sequencing appli…
Influence of the environment and probes on rapid DNA sequencing via transverse electronic transport
Johan Lagerqvist, Michael Zwolak, Massimiliano Di Ventra
We study theoretically the feasibility of using transverse electronic transport within a nanopore for rapid DNA sequencing. Specifically, we examine the effects of the environment…
Comment on "Characterization of the tunneling conductance across DNA bases"
Johan Lagerqvist, Michael Zwolak, Massimiliano Di Ventra
In a recent article, Zikic {\it et al.} [Phys. Rev. E {\bf 74}, 011919 (2006)] present first-principles calculations of the DNA nucleotides electrical conductance. They report qual…
