Abstract: This invention relates to the field of nanotechnology. Specifically the invention describes a nanosensor for the detection of an analyte in which the redox potential in solution is altered thereby causing changes in carbon nanotube conductance.

Abstract: Nanosensors for detecting target analytes and methods of detecting analytes have been developed in which a small molecule effector concentration is altered thereby causing changes in carbon nanotube conductance. The nanosensor operates in a homogeneous format, not requiring the immobilization of the target analyte for detection.

Abstract: Nanosensors for detecting analytes and methods of detecting analytes have been developed in which the redox potential of a redox effector in solution is altered thereby causing changes in carbon nanotube conductance. The analyte may be detected in solution, eliminating the need for immobilizing the analyte on a support.

Abstract: Nucleic acid molecules in a stabilized solution such as single stranded DNA and RNA were able to disperse high concentration of bundled carbon nanotubes into aqueous solution.

Abstract: Carbon nanotubes have been reversibly and readily oxidized and reduced with common chemicals in solution, thereby allowing the nanotubes to be used as catalysts for chemical reactions and as stable charge storage devices.

Abstract: Protein polymers coated with a metal are provided. New methods are described for the preparation of tubulin-based microtubules such that they may be coated, by an electroless plating method, with gold particles of <20 nm in diameter without prior reaction with noble metal catalysts. The gold particle deposition can occur in suspension or on microtubules lying on a surface. Gold enhancement of the gold-particle coating and annealing results in ohmic conductance that is within a factor of ten of the resistivity of bulk gold. These methods are likely to be applicable to other protein polymers.

Abstract: A light collector for use with a photodetector that provides uniform photodetector output response over a polar angular range regardless of the polar angle of incidence of light upon the collector is disclosed. The light collector comprises a generally spheroidally-shaped light direction changer having a light diffusing surface, and a generally spheroidally-shaped polar attenuator. The geometric center of the photosensitive surface of the photodetector is adjacent to the vertex of the generally spheroidally-shaped light direction changer.
