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.

Abstract: A process for monitoring binding events, a coating compound, and a device for monitoring binding events are disclosed. The process includes providing two reservoirs that contain an electrically conductive fluid, wherein the reservoirs are separated by a membrane having a nanopore. The process also includes selecting a target compound, selecting a ligand based on the selection of the target compound, and preparing a coating that includes the coating compound, wherein the coating compound includes the ligand and a moiety that immobilizes the ligand. Additionally, the process includes applying the coating to the inner surface of the nanopore, adding the target compound to a conductive liquid in the first chamber, establishing a voltage gradient across the membrane, and electrically monitoring translocation of the target molecule. The device includes the reservoirs and the membrane having the coated nanopore.
