Patent number: 7449757Abstract: A nanoelectronic device includes a nanostructure, such as a nanotube or network of nanotubes, disposed on a substrate. Nanoparticles are disposed on or adjacent to the nanostructure so as to operatively effect the electrical properties of the nanostructure. The nanoparticles may be composed of metals, metal oxides, or salts, and nanoparticles composed of different materials may be present. The amount of nanoparticles may be controlled to preserve semiconductive properties of the nanostructure, and the substrate immediately adjacent to the nanostructure may remain substantially free of nanoparticles. A method for fabricating the device includes electrodeposition of the nanoparticles using one or more solutions of dissolved ions while providing an electric current to the nanostructures but not to the surrounding substrate.Type: GrantFiled: September 20, 2004Date of Patent: November 11, 2008Assignee: Nanomix, Inc.Inventors: Keith Bradley, Alona J.

Publication number: 20080216558Abstract: A surface acoustic wave based CO2 sensor using carbon nanotubes as the sensitive layer fabricated by combining surface acoustic wave (SAW) devices and nanotechnology. The device structure consists of the gas sensitive material between the input and output interdigital transducers (IDTs) of a SAW device. The CO2 gas gets adsorbed on nanotubes when the carbon nanotube based SAW sensor is exposed to CO2 at room temperature and/or at elevated temperature, which in turn changes conductivity of the carbon nanotube. This conductivity change will affect the velocity of the SAW traveling across the nanotubes and will give a frequency change which corresponds to the percentage of the CO2 molecules adsorbed by the nanotubes.Type: ApplicationFiled: March 8, 2007Publication date: September 11, 2008Inventors: Sarin Anakkat Koyilothu, Raju A.

Patent number: 7341774Abstract: An electronic or opto-electronic device or a chemical sensor comprising: an interpenetrating network of a nanostructured high surface area to volume ratio film material and an organic/inorganic material forming a nanocomposite. The high surface area to volume film material is obtained onto an electrode substrate first, such that the nano-scale basic elements comprising this film material are embedded in a void matrix while having electrical connectivity with the electrode substrate. For example, the film material may comprise an array of nano-protrusions electrically connected to the electrode substrate and separated by a void matrix. The interpenetrating network is formed by introducing an appropriate organic/inorganic material into the void volume of the high surface area to volume film material. Further electrode(s) are defined onto the film or intra-void material to achieve a certain device.Type: GrantFiled: March 14, 2005Date of Patent: March 11, 2008Assignee: The Penn State Research FoundationInventors: Ali Kaan Kalkan, Stephen J.
