Claim Text:
1. A sensor for detecting a detection target, the sensor comprising: a field-effect transistor having an insulator overlying the substrate and covering a portion of the channel; an interaction-sensing gate overlying the insulator, the interaction-sensing gate having a specific substance that is capable of selectively interacting with the detection target; a gate for applying a gate voltage to adjust a characteristic of the field-effect transistor; wherein the detection target changes the characteristic of the field-effect transistor when interacting with the specific substance; wherein the interaction-sensing gate is not in direct contact with the source electrode and is not in direct contact with the drain electrode; wherein the insulator covers only a middle portion of the channel; and wherein the specific substance is disposed on only a limited portion of the interaction sensing gate; wherein the channel comprises a carbon nano tube, the carbon nano tube being bent between the source electrode and the drain electrode at room temperature.
