<p>A chemical substance sensor is formed by arranging a sensor chip on a microcartridge formed with a micropassage and further arranging a prism on this sensor chip. In the sensor chip, a metal thin film is formed on one surface of a substrate, and an immobilizer is further formed thereon. In order to detect a chemical substance with the chemical substance sensor, a solution containing a sample and odorant binding protein is fed to the micropassage for immobilizing the odorant binding protein to the immobilizer. The chemical substance contained in the sample is detected on the basis of the quantity of immobilization of the odorant binding protein.</p> |
