Abstract
A nanopore device for molecular characterization that includes a supporting substrate. The supporting substrate has at least one nanopore where the nanopore is a carbon nanotube of a first diameter. The nanodevice is configured to provide a stimulus to the carbon nanotube causing the first diameter to change to a second diameter. The nanopore device also includes a device configured to apply the stimulus to the nanopore. The nanopore device further includes an electrical circuit configured to measure an electrical property across the nanopore, where there is a change in the electrical property when a molecule traverses the nanopore.
