  • Devices for optochemical detecting of vapors and particulates using porous photonic crystals infiltrated with sensory emissive organics
    Patent number: 8330958
    Abstract: An optochemical detector for detecting various chemical compounds and comprising a flow cell incorporating the sensory element constructed of an organic-inorganic emissive nanocomposite which luminescence spectral response is specific to exposed target vapors and particulates. The change in the luminescent spectral response is measured during this exposure. The detector is equipped with air-jet sampling system functioning in real-time mode for delivery of vapors and particulates to sensory element.

  • Optochemical sensors for the detection of low pressure vapors based on porous semiconductors and emissive organics
    Patent number: 8003403
    Abstract: A chemical sensor for detecting organic or inorganic target vapors and comprising a silicon member having a silicon surface with semiconductor pores therein, at least one luminescent sensory material entrapped in the semiconductor pores. The luminescent spectral material is exposed to the target vapors, wherein an excitation of the at least one luminescent sensory material results in a luminescent spectral response due to emission interference. The change in the luminescent spectral response is measured during this exposure.

  • Amplified sensitivity of porous chemosensors based on bernoulli effect
    Patent number: 7908902
    Abstract: A method of vapor sampling and its delivery to the porous sensory element(s) employed in chemical detectors/sensors for vapor(s) identification and quantification. The sampling and delivery system comprises a flow cell in which a sensory membrane is placed parallel to the flow, while an additional flow normal to the membrane is introduced using the Bernoulli effect. The bi-directional flow of vapors increases the interactions between the sensory material and vapor molecules, and enhances sensitivity.

  • OPTICAL NANOPOROUS SENSORS FOR DETECTION OF WATER BASED VAPORS AND THEIR LEAKAGE FROM SEALED CONTAINERS
    Publication number: 20100328646
    Abstract: An optical sensor for detecting water vapors and water based vapors and comprising a semiconductor member having a semiconductor surface with hydrophilic pores therein. An illumination of the semiconductor surface by white light produces the reflectance spectral profile due to light spectral. The spectral profile is exposed to the water vapors and the change in the reflectance spectral response is measured during this exposure.
