    摘要: This invention enables a sensitivity enhancement in the detection of molecular compounds. A mass spectrometry analyte support with nanotube anchors are used to concentrate MALDI samples, specifically samples prepared with water-insoluble matrix compounds, on the anchor spot. The surface structure is established through patterned carbon nanotube anchor growth, providing a nucleation center for analyte and reducing sample precipitation on the surrounding MALDI wafer. Also disclosed is a method of creating a mass spectrometry support using patterned metal catalyst to grow carbon nanotubes. The carbon nanotubes enhance nucleation on specific areas of a sample plate to concentrate analyte/matrix deposit during droplet evaporation.

    摘要: This invention enables a sensitivity enhancement in the detection of molecular compounds. A mass spectrometry analyte support with nanotube anchors are used to concentrate MALDI samples prepared with water-insoluble matrix compounds on the anchor spot. A matrix solution mixed with analyte molecules is spotted onto a specialized MALDI plate using carbon nanotubes to selectively nucleate the analyte. The spot diameter of the target is usually several orders of magnitude larger than traditional supports, and led to lateral concentration for non-aqueous based matrices and produced a final dried matrix/analyte spot that was approximately the diameter of the laser spot at the point of investigation. The carbon nanotubes enhance nucleation on specific areas of a sample plate to concentrate analyte/matrix deposit during droplet evaporation, and demonstrate an increase in signal to noise ratio and an improved detection capability of low analyte concentrations compared to the standard MALDI preparation technique.

    摘要: A method of producing an integrated circuit with a carbon nanotube is disclosed. The integrated circuit includes a source, a drain, and a gate, and the source and the drain are positioned on the gate. A catalytic material is deposited onto the source. The catalytic material is then subjected to chemical vapor deposition. This initiates growth of the carbon nanotube such that the carbon nanotube extends from the source. Next, the carbon nanotube is bent toward the integrated circuit such that the carbon nanotube extends between the source and the drain to render the circuit operable.

    摘要: A method of forming a smooth thin film on a substrate within a short deposition time, the method comprising introducing ionic substances (salts, acids, bases) to a polymeric solution to be sprayed. These ions attach to the polymer strands in solution, increasing their charge to mass ratio. This results in mutual repulsion of the strands during the spray process and produces a smooth film, even at relatively high polymeric solution concentrations. A side effect of this process is the introduction of impurities (the added ions) to the polymer thin film. The proper choice of ionic compound allows a dissolution step to be used to “clean” the polymer film after deposition, using the solubility characteristics of the thin film versus the ionic compound.

    摘要: An electrospray (ES)-based deposition system enabling the coating an impervious substrate, such as a glass slide, with biological materials in a vacuum. Distilled water or a buffer is used as the solvent; no other solvents are used thereby eliminating hazardous waste from the process. Movement across differential pumping stages causes evaporation of the solvent occurs resulting in shrinkage of the remaining constituents with an increase of the charge density. The resulting ion beam enters a vacuum chamber and the beam impinges on the substrate, whereby a thin layer is deposited thereon. The spray can be focused to a specific area allowing patterning of the substrate if desired. The amount of coating can be controlled and a specified number of coats of the same or different molecules can be added to the surface.

    摘要: The present invention provides a method for the selective growth of single carbon nanotubes (CNT) on the tip apex of a conventional cantilever. Selective CNT growth is established by coating the backside of a cantilever, having a through-hole at a tip apex, with a catalyst material followed by a cover layer. The exposed catalyst at the bottom of the hole at the apex of the cantilever induces growth of a single CNT at this location.
