摘要： The present invention provides a transistor-based polyamine sensor with which it is possible to detect a polyamine easily and with high sensitivity. Specifically, the present invention provides a transistor-based polyamine sensor comprising a detection site, wherein an organic compound containing a carboxy group and a thiol group is immobilized on all or part of the surface of the detection site via the thiol group of the organic compound, a heavy metal ion is bound to the carboxy group of the organic compound, and a change in threshold voltage caused by bonding of the heavy metal ion to a polyamine is measured to detect the polyamine.
