The present invention relates to the calibration of devices using a secondary binding agent or reference material. In one embodiment, the present invention provides a method of calibrating a nanosensor by providing a nanosensor comprising an analyte binder attached to a reference binder, extracting a calibration curve from binding a reference material to the reference binder, and calibrating the nanosensor by using the calibration curve to correct for device variation.
摘要:
Indium oxide nanowires are used for determining information about different chemicals or Biologics. Chemicals are absorbed to the surface of the nanowires, and cause the semiconducting characteristics of the Nanowires to change. These changed characteristics are sensed, and used to determine either the presence of the materials and/or the concentration of the materials. The nanowires may be between 10 and 30 nm in diameter, formed using a comparable size particle of catalyst material. The nanowires may then be used as part of the channel of a field effect transistor, and the field effect transistor is itself characterized.

A method for growing a graphene layer on a metal foil includes placing a vessel into a chemical vapor deposition chamber, the vessel having a metal foil positioned therein. The method includes evacuating the chemical vapor deposition chamber, introducing hydrogen gas into the chamber to achieve a first pressure less than atmospheric pressure, heating the atmosphere in the chamber to anneal the metal foil, introducing methane and hydrogen into the chamber to achieve a second pressure less than atmospheric pressure.

An electrode includes a first free-standing carbon network, an active material deposited above the first free-standing carbon network, and a second free-standing carbon network covering the active material. The first and second carbon networks are a binder, a conductive additive and a current collector to the electrode.

A separated carbon nanotube-based active matrix organic light-emitting diode (AMOLED) device including a substrate and transistors. Each transistor includes an individual back gate patterned on the substrate and a gate dielectric layer disposed over the substrate. An active channel including a network of separated semiconducting nanotubes is disposed over a functionalized surface of the gate dielectric layer. A source contact and a drain contact are formed on two ends of the active channel, with the network of separated nanotubes between the source contact and the drain contact. An organic light-emitting diode (OLED) display device is coupled to the drain of one of the transistors. A system includes a display control circuit having a substrate, with scan lines, data lines, and AMOLED devices formed on the substrate, with each AMOLED device coupled to one of the scan lines and one of the data lines.

An electrochemical capacitor includes a first electrode including a first flexible substrate, a second electrode including a second flexible substrate, and an electrolyte. The first electrode includes a first layer of single-walled carbon nanotubes inkjetted on the first flexible substrate and a layer of first nanowires disposed on the first layer of single-walled carbon nanotubes. The second electrode includes a second layer of single-walled carbon nanotubes inkjetted on the second flexible substrate and a layer of second nanowires disposed on the second layer of single-walled carbon nanotubes. The electrolyte is sandwiched between the layer of first nanowires and the layer of second nanowires to form the electrochemical capacitor. A flexible energy storage device includes a first flexible substrate, a second flexible substrate, and one or more electrochemical capacitors formed between the first flexible substrate and the second flexible substrate. The flexible energy storage device can be wearable.
