SENSOR UNIT AND REACTION FIELD CELL UNIT AND ANALYZER

摘要

A transistor-based sensor unit which has, in order to enhance ease of analysis, a transistor unit (103) provided with a substrate (108), a source electrode (111) and a drain electrode (112) provided on the substrate (108), a channel (113) as a current passage between the source electrode (111) and the drain electrode (112), and a detecting sensing gate (117), wherein a gate body (115) fixed to the substrate (108) and a sensing unit (116) that can electrically conduct with the gate body (115) fixed with a specific material (123) selectively interacting with a material to be detected are provided to the detecting sensing gate (117) of the sensor unit for detecting the material to be detected.
