US Patent:
20040038251, Feb 26, 2004
Filed:
Mar 4, 2003
Appl. No.:
10/379022
Inventors:
Richard Smalley - Houston TX, US
Robert Hauge - Houston TX, US
W. Kittrell - Houston TX, US
Ramesh Sivarajan - Houston TX, US
Michael Strano - Houston TX, US
Sergei Bachilo - Houston TX, US
R. Weisman - Houston TX, US
International Classification:
C12Q001/68
G01N033/53
US Classification:
435/006000, 435/007100
Abstract:
The invention relates to macroscopic amounts of (n, m) type single-wall carbon nanotubes and sensing and monitoring devices comprising specific nanotube types. Selected (n, m)-type fractions of single-wall carbon nanotubes are separated from a suspension of mixed single-wall carbon nanotubes are individually dispersed and isolated. The nanotubes are isolated and precluded from reassociating with other nanotubes by encasing the nanotube with a non-perturbing molecular species, such as surfactant molecules or polymers that can wrap around the nanotube. In contrast to metallic single-wall carbon nanotubes, semiconducting single-wall carbon nanotubes have been found to fluoresce in the near-IR region of the electromagnetic spectrum. The nanotubes are very sensitive to environmental perturbations and the nanotube's fluorescence profile will be affected by these perturbations. Thus, the nanotubes can be used as sensors for a wide variety of applications, such as gas concentrations and pH, as well as fluorescent tags for biological mapping of malignant cell activity.

US Patent:
20040040834, Mar 4, 2004
Filed:
Mar 4, 2003
Appl. No.:
10/379273
Inventors:
Richard Smalley - Houston TX, US
Robert Hauge - Houston TX, US
W. Kittrell - Houston TX, US
Ramesh Sivarajan - Houston TX, US
Michael Strano - Houston TX, US
Sergei Bachilo - Houston TX, US
R. Weisman - Houston TX, US
International Classification:
H05F003/00
US Classification:
204/164000
Abstract:
The invention relates to a process for sorting and separating a mixture of (n, m) type single-wall carbon nanotubes according to (n, m) type. A mixture of (n, m) type single-wall carbon nanotubes is suspended such that the single-wall carbon nanotubes are individually dispersed. The nanotube suspension can be done in a surfactant-water solution and the surfactant surrounding the nanotubes keeps the nanotube isolated and from aggregating with other nanotubes. The nanotube suspension is acidified to protonate a fraction of the nanotubes. An electric field is applied and the protonated nanotubes migrate in the electric fields at different rates dependent on their (n, m) type. Fractions of nanotubes are collected at different fractionation times. The process of protonation, applying an electric field, and fractionation is repeated at increasingly higher pH to separated the (n, m) nanotube mixture into individual (n, m) nanotube fractions. The separation enables new electronic devices requiring selected (n, m) nanotube types.

US Patent:
20080014654, Jan 17, 2008
Filed:
Nov 16, 2005
Appl. No.:
11/281784
Inventors:
R. Weisman - Houston TX, US
Sergei Bachilo - Houston TX, US
John-David Rocha - Missouri City TX, US
John Casey - Houston TX, US
Assignee:
William Marsh Rice University - Houston TX
International Classification:
G01N 21/64
US Classification:
436172000, 436171000, 422082080
Abstract:
The present invention is directed toward methods and devices for analyzing populations of single-wall carbon nanotubes (SWNTs) on the basis of their fluorescence properties and the comparison of said properties to fluorescence profiles of pre-determined SWNT compositions. Generally, such analyzing yields information about the composition of the SWNTs within said population. Such information includes, for example, the relative abundances of semiconducting SWNTs, the diameter distribution of such SWNTs, and the relative abundances of one or more particular SWNT species—as identified by one or more specific nanotube indices (n,m). The methods and devices of the present invention provide for the analysis of SWNT compositions in a rapid and efficient manner.

G01L 1/24
G01N 21/359
US Classification:
25033907
Abstract:
In some embodiments, the present invention provides methods of detecting strain associated with an object by: (1) irradiating a composition that has been applied to the object, where the composition comprises semiconducting single-walled carbon nanotubes; (2) measuring an emission from the irradiated composition, where the emission comprises near infrared emission; and (3) correlating the near infrared emission to the presence or absence of strain associated with the object. In some embodiments, the aforementioned steps occur without physically contacting the object or the composition. In some embodiments, the aforementioned steps occur without utilizing Raman spectroscopy. Further embodiments of the present invention also include a step of applying the composition to the object.
