Abstract: A nanosensor for detecting molecule characteristics includes a membrane having an opening configured to permit a charged carbon nanotube to pass but to block a molecule attached to the carbon nanotube. The opening is filled with an electrolytic solution. An electric field generator is configured to generate an electric field relative to the opening to drive the charged carbon nanotubes through the opening. A sensor circuit is coupled to the electric field generator to sense current changes due to charged carbon nanotubes passing into the opening, and to bias the electric field generator to determine a critical voltage related to a force of separation between the carbon nanotube and the molecule.

Abstract: A process of sorting metallic single wall carbon nanotubes (SWNTs) from semiconducting types by disposing the SWNTs in a dilute fluid, exposing the SWNTs to a dipole-inducing magnetic field which induces magnetic dipoles in the SWNTs so that a strength of a dipole depends on a conductivity of the SWNT containing the dipole, orienting the metallic SWNTs, and exposing the SWNTs to a magnetic field with a spatial gradient so that the oriented metallic SWNTs drift in the magnetic field gradient and thereby becomes spatially separated from the semiconducting SWNTs. An apparatus for the process of sorting SWNTs is disclosed.
