MOLECULAR TRANSISTOR

摘要

Fluidic nanotube devices and methods for their use are provided wherein the flow of charged molecules through a channel is controlled by the voltage potential of a gate electrode. In at least some embodiments, a molecular transistor is provided that includes a channel having a diameter such that only one target molecule at a time may traverse the channel. The channel may be a carbon nanotube that is electrically isolated from, and in communication with, a gate electrode. Methods are provided for controlling the flow of an individual molecule through the channel and for detecting a single chemical reaction.
