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.
