  • Publication number: 20110246086
    Abstract: A method and apparatus for detecting a particular chemical in a sample, includes placing the sample in contact with a semiconductive material provided on a flow cell. An electrical characteristic of the semiconductive material is detected by an interdigitated electrode, and a first signal indicative thereof of output. An optical characteristic of the semiconductive material is detected by a photodetector and a second signal indicative thereof is output. Based on the first and second signals, it is determined by a processor as to whether or not the particular chemical is present in the sample.

  • Publication number: 20100001211
    Abstract: A method and apparatus for increasing detection characteristics of a chemical sensor array that has been previously exposed to an agent in order to detect and categorize the agent. Ultraviolet light at a predetermined wavelength is applied to the chemical sensor array, in order to desorb the agent from the chemical sensor array, so as to increase a resistance of the chemical sensor array. Alternatively or together with the ultraviolet light, a bias voltage is applied to at least one biasing electrode making up the chemical sensor array, in order to desorb the agent from the chemical sensor array, so as to increase the resistance of the chemical sensor array. The chemical sensor array may be a carbon nanotube sensor array.
