A method for single-molecule detection is provided and uses a carbon nanotube having a probe entity attached thereto to define a first state of the carbon nanotube. The carbon nanotube is introduced to a target entity to define a second state of the carbon nanotube. The electrical conductance of the carbon nanotube in the first and second states is compared to detect the presence of a biomolecular entity. A system for single-molecule detection including a carbon nanotube is also provided.

Systems and methods for single-molecule detection using nanotubes

Organic perylene diimide-based compounds are provided. Methods of producing the organic compounds is also provided as well as methods of their use including, among other things, their use as organic semiconductor materials.

Organic semiconductor compounds and methods of use

A solid-state material comprising a solid-state compound is provided. The solid-state compound has the formula: [Cluster1][Cluster2], where Cluster1 can be a metal chalcogenide molecular cluster, Cluster2 a carbon cluster, and n the number of Cluster2 clusters in the solid-state compound. A method of forming a solid-state material is also provided.

A laminated graphene device is demonstrated as a cathode. In one example the devices include organic photovoltaic devices. The measured properties demonstrate work-function matching via contact doping. Devices and method shown also provide increased power conversion efficiency due to transparency. These findings indicate that flexible, light-weight all carbon devices, such as solar cells, can be constructed using graphene as the cathode material.

Graphene electrodes for electronic devices

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.

An apparatus or method can include forming a graphene layer including a working surface, forming a polyvinyl alcohol (PVA) layer upon the working surface of the graphene layer, and forming a dielectric layer upon the PVA layer. In an example, the PVA layer can be activated and the dielectric layer can be deposited on an activated portion of the PVA layer. In an example, an electronic device can include such apparatus, such as included as a portion of graphene field-effect transistor (GFET), or one or more other devices.

The present invention generally relates to the fabrication of molecular electronics devices from molecular wires and Single Wall Nanotubes (SWNT). In one embodiment, the cutting of a SWNT is achieved by opening a window of small width by lithography patterning of a protective layer on top of the SWNT, followed by applying an oxygen plasma to the exposed SWNT portion. In another embodiment, the gap of a cut SWNT is reconnected by one or more difunctional molecules having appropriate lengths reacting to the functional groups on the cut SWNT ends to form covalent bonds. In another embodiment, the gap of a cut SWNT gap is filled with a self-assembled monolayer from derivatives of novel contorted hexabenzocoranenes. In yet another embodiment, a device based on molecular wire reconnecting a cut SWNT is used as a sensor to detect a biological binding event.
