20090018826 | Methods, Systems and Devices for Speech Transduction - Methods, systems, and devices for speech transduction are disclosed. One aspect of the invention involves a computer-implemented method in which a computer receives far-field acoustic data acquired by one or more microphones. The far-field acoustic data are analyzed. The far-field acoustic data are modified to reduce characteristics of the far-field acoustic data that are incompatible with human speech characteristics of near-field acoustic data. | 01-15-2009 |

20090170725 | Methods of producing carbon nanotubes using peptide or nucleic acid micropatterning - The methods, apparatus and systems disclosed herein concern ordered arrays of carbon nanotubes. In particular embodiments of the invention, the nanotube arrays are formed by a method comprising attaching catalyst nanoparticles 140, 230 to polymer 120, 210 molecules, attaching the polymer 120, 210 molecules to a substrate, removing the polymer 120, 210 molecules and producing carbon nanotubes on the catalyst nanoparticles 140, 230. The polymer 120, 210 molecules can be attached to the substrate in ordered patterns, using self-assembly or molecular alignment techniques. The nanotube arrays can be attached to selected areas 110, 310 of the substrate. Within the selected areas 110, 310, the nanotubes are distributed non-randomly. Other embodiments disclosed herein concern apparatus that include ordered arrays of nanotubes attached to a substrate and systems that include ordered arrays of carbon nanotubes attached to a substrate, produced by the claimed methods. In certain embodiments, provided herein are methods for aligning a molecular wire, by ligating the molecular wire to a double stranded DNA molecule. | 07-02-2009 |
20090262994 | MODEL-BASED FUSION OF SCANNING PROBE MICROSCOPIC IMAGES FOR DETECTION AND IDENTIFICATION OF MOLECULAR STRUCTURES - In certain embodiments of the invention, a plurality of images of one or more subjects may be captured using different imaging techniques, such as different modalities of scanning probe microscopy. Parameters may be estimated from the plurality of images, using one or more models of known molecular structures to provide a model-based analysis. The estimated parameters may be fused, with further input from physical models of known molecular structures. The fused parameters may be used to characterize the subjects. Such characterization may include the detection and/or identification of specific molecular structures, such as proteins, peptides and/or nucleic acids of known sequence and/or structure. In some embodiments of the invention the structural characterizations may be used to identify previously unknown properties of a subject molecule. | 10-22-2009 |
20100151454 | MICROFLUIDIC APPARATUS, SYSTEMS, AND METHODS FOR PERFORMING MOLECULAR REACTIONS - Disclosed herein are methods, apparatuses, and systems for performing nucleic acid sequencing reactions and molecular binding reactions in a microfluidic channel. The methods, apparatuses, and systems can include a restriction barrier to restrict movement of a particle to which a nucleic acid is attached. Furthermore, the methods, apparatuses, and systems can include hydrodynamic focusing of a delivery flow. In addition, the methods, apparatuses, and systems can reduce non-specific interaction with a surface of the microfluidic channel by providing a protective flow between the surface and a delivery flow. | 06-17-2010 |
20100240870 | Composite organic-inorganic nanoclusters - Composite organic-inorganic nanoclusters (COINs) are provided that produce surface-enhanced Raman signals (SERS) when excited by a laser. The nanoclusters include metal particles and a Raman-active organic compound. The metal required for achieving a suitable SERS signal is inherent in the nanocluster and a wide variety of Raman-active organic compounds and combinations thereof can be incorporated into the nanocluster. In addition, polymeric microspheres containing the nanoclusters and methods of making them are also provided. The nanoclusters and microspheres can be used, for example, in assays for multiplex detection of biological molecules. | 09-23-2010 |
20120196384 | BIOSENSOR UTILIZING A RESONATOR HAVING A FUNCTIONALIZED SURFACE - Systems and methods for detecting the presence of biomolecules in a sample using biosensors that incorporate resonators which have functionalized surfaces for reacting with target biomolecules. In one embodiment, a device includes a piezoelectric resonator having a functionalized surface configured to react with target molecules, thereby changing the mass and/or charge of the resonator which consequently changes the frequency response of the resonator. The resonator's frequency response after exposure to a sample is compared to a reference, such as the frequency response before exposure to the sample, a stored baseline frequency response or a control resonator's frequency response. | 08-02-2012 |
