    Abstract: 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.

    Abstract: The invention includes compositions, devices, and methods for analyzing a polymer and/or polymer unit. The polymer may be a homo- or hetero-polymer such as DNA, RNA, a polysaccharide, or a peptide. The device includes electrodes that form a tunnel gap through which the polymer can pass. The electrodes are functionalized with a reagent attached thereto, and the reagent is capable of forming a transient bond to a polymer unit. When the transient bond forms between the reagent and the unit, a detectable signal is generated and used to analyze the polymer.

    Abstract: The present invention provides a device for analyzing the composition of a heteropolymer comprising a carbon nanotube through which the heteropolymer is driven by electrophoresis. The carbon nanotube also serves as one electrode in a reading circuit. One end of the carbon nanotube is held in close proximity to a second electrode, and each end of the carbon nanotube is functionalized with flexibly-tethered chemical-recognition moieties, such that one will bind one site on the emerging polymer, and the second will bind another site in close proximity, generating an electrical signal between the two electrodes when the circuit is completed by the process of chemical recognition.
