    摘要： A film of a coating material is produced on a substrate by a pulsed laser deposition method in which the material that forms the coating material is first combined with a matrix material to form a target. The target is then exposed to a source of laser energy to desorb the matrix material from the target and lift the coating material from the surface of the target. The target and the substrate are oriented with respect to each other so that the lifted coating material is deposited as a film upon said substrate. The matrix material is selected to have the property of being more volatile than the coating material and less likely than the coating material to adhere to the substrate. The matrix material is further selected as having the property such that when the target is exposed to a source of laser energy, the matrix material desorbs from the target and lifts the coating material from the surface of the target. In another aspect of the invention, a method of making an improved chemical or biochemical sensing device that includes a chemoselective or bioselective coating on a substrate is carried out by coating the substrate by pulsed laser deposition.

    摘要： In the invention, a collection device includes a first micro scale plate having a sorbent surface and a through hole. The through hole provides for the passage of an analyte fluid flow through the plate and it has a volume and geometry to provide contact between the fluid and the sorbent surface in an amount effective to absorb a sufficient amount of analyte for subsequent detection of the analyte. The sorbent surface can be provided by a sorbent coating such as an active sensing film, e.g. a conducting or optically active material, examples of which include conducting polymers, polymer/carbon composites, carbon nanotubes. and dye-containing materials. The analyte collection device preferably includes a heating source, e.g. a heating element formed from a resistive trace, or a plurality of resistive traces on or within the first microscale plate, for effecting a thermal release of collected analyte from the plate.

These polymeric materials are primarily designed to sorb hydrogen bond basic analytes such as organophosphonate esters (nerve agents and precursors) and nitro-substituted compounds (explosives).

    摘要： A method and apparatus for interrogating a resonator to monitor its resonance characteristics (e.g. resonant frequency) in an especially energy efficient manner, particularly changes to the characteristics over time. The resonator is pulsed and the response thereto sampled. By comparison of samples of the response to sequential pulses, sampled at the same times after pulse initiation, one can infer phase changes between the responses, and hence infer changes in resonance characteristics. Preferably, one calibrates the resonator's time response initially as a reference, which permits subsequent determination of the resonance state with only one digital sample per pulse. In one embodiment, the invention this detection scheme is used as a chemical detector. The resonator is an electo-acoustic device, having plural Bragg gratings, with a different adsorptive material atop each grating which adsorbs one selected chemical particularly well. Absorption causes the weight of material to increase, changing the resonance characteristics of the gratings. A single pulse launched into the SAW will cause reflections from each of the Bragg cells which are staggered in time, and hence separately detectable. The resonance of each grating is then tracked as above described, and changes thereto over time indicates the amount of material adsorbed.

    摘要： The present invention is directed to a method for non-contact or stand off chemical detection by selectively exciting one or more analytes of interest using an IR source tuned to at least one specific absorption band without significantly decomposing the analyte and determining if the analyte is present by comparing emitted photons with an IR detector signal made before and during or shortly after exciting the analyte. Another embodiment provides a method for non-contact or stand off chemical detection by selectively exciting one or more analytes of interest using an IR source tuned to at least one specific absorption band without significantly decomposing the analyte, wherein the analyte is excited sufficiently to generate a vapor plume, and wherein the plume is examined to detect the presence of the analyte. Additionally, the present invention provides for a system for non-contact or stand off chemical detection.
