Electrochemistry in nanopore/electrode structures - from pore fabrication to DNA sequencing-by-tunneling

Keywords: nanopore sensing, DNA sequencing, nanofabrication, single-molecule biophysics


I will present results from my research group on nanopore-based single-biomolecule sensor with particular focus on electrode/nanopore structures. To this end, electrochemical concepts can be used for fabrication purposes, as well as for increased temporal and spatial resolution in single-biomolecule sensing. An example is the integration of a functional tunneling junction into a nanopore device, paving the way to ultra-fast and label-free DNA sequencing-by-tunneling.
