PROBLEM TO BE SOLVED: To provide a transistor heavy metal ion sensor capable of simply detecting heavy metal ions such as cadmium and easily fabricating a device.SOLUTION: A coordination bond is used in a detection portion. The detection portion has a configuration in which a pyridine derivative is fixed to a metal surface of an extension gate by a sulfide group. In the pyridine derivative, a transistor heavy metal ion sensor is configured which detects a heavy metal ion by measuring change in threshold value voltage or drain current value generated by a bond of heavy metal ions.SELECTED DRAWING: None |
