Improved gas sample preprocessing is provided for scanning optical spectroscopic analysis instruments by tailoring characteristic gas handling times to the scan time Tof the analysis instrument. In particular, for sample preconcentration, the desorption duration Tof the sample preconcentrator should be ≥2T. For gas chromatography, the elution duration Tof relevant eluted species should be ≥2T. This advantageously avoids having significant changes in the gas sample within the analysis instrument as a scan is being performed.

Thermal desorption preconcentrator adapted for spectroscopic gas analysis

Methods, systems, and apparatuses for nanowire deposition are provided. A deposition system includes an enclosed flow channel, an inlet port, and an electrical signal source. The inlet port provides a suspension that includes nanowires into the channel. The electrical signal source is coupled to an electrode pair in the channel to generate an electric field to associate at least one nanowire from the suspension with the electrode pair. The deposition system may include various further features, including being configured to receive multiple solution types, having various electrode geometries, having a rotatable flow channel, having additional electrical conductors, and further aspects.

Methods and systems for electric field deposition of nanowires and other devices

System, including apparatus and methods, for aspirating at least a portion of an emulsion from a well using a tip. In some embodiments, the tip may have a flat end and an inlet surrounded by the flat end. The well may have a floor with one or more surface features that prevent uninterrupted circumferential contact of the flat end of the tip with any region of the floor. In some embodiments, the tip may not have a flat end. In some embodiments, the well may have a port that guides the tip to the floor with the tip slanted with respect to the floor. Methods of making a device that includes the well are also disclosed.

The present invention provides methods and systems for nanowire alignment and deposition. Energizing (e.g., an alternating current electric field) is used to align and associate nanowires with electrodes. By modulating the energizing, the nanowires are coupled to the electrodes such that they remain in place during subsequent wash and drying steps. The invention also provides methods for transferring nanowires from one substrate to another in order to prepare various device substrates. The present invention also provides methods for monitoring and controlling the number of nanowires deposited at a particular electrode pair, as well as methods for manipulating nanowires in solution.

Methods for nanowire alignment and deposition

This invention provides nanowire based molecular sensors and methods for detecting analytes in a microfluidic system. Methods for sensing analytes include detecting changed electrical parameters associated with contact of a nanowire with the analyte in a microfluidic system. Sensors of the invention include nanowires mounted in microchambers of a microfluidic system in electrical contact with the detector, whereby electrical parameter changes induced in the nanowire by the analyte can be monitored by the detector.

The present invention is directed to methods to produce, process, and exploit nanomaterials, and particularly elongated nanowire materials. The invention provides a method for producing nanowires that includes providing a thin film of a catalyst material with varying thickness on a substrate, heating the substrate and thin film, such that the thin film disassociates at the relatively thinner regions and vapor depositing a semiconductor onto the substrate to produce nanowires. A method is also provided in which two or more thin films of different materials are overlayed over a substrate, selectively etching the first underlying thin film to create a plurality of islands of the second thin film that mask portions of the first thin film and expose other portions and growing nanowires on the first thin film. Additional methods for producing nanowires are provided.
