A single-molecule nanopore device detects DNA polymerase activity with single-nucleotide resolution.

ABSTRACT: The ability to monitor DNA polymerase activity with single-nucleotide resolution has been the cornerstone of a number of advanced single-molecule DNA sequencing concepts. Toward this goal, we report the first observation of the base-by-base DNA polymerase activity with single-base resolution at the single-molecule level. We describe the design and characterization of a supramolecular nanopore device capable of detecting up to nine consecutive DNA polymerase-catalyzed single-nucleotide primer extensions with high sensitivity and spatial resolution (
