Abstract

The present invention provides a charged substance detector capable of detecting charged substances easily and quickly without complicating the construction of the detector, a method of using the charged substance detector and a detection panel. The charged substance detector comprises: a detection panel 1 having a plurality of reaction electrodes 2 arrayed in matrix, on which are immobilized reaction charged substances reacting specifically with target charged substances; and a conduction control device 4 having a matrix of wires 3 crossing each other at points corresponding to the matrix-arrayed reaction electrodes 2 of the detection panel 1, and being capable of selectively energizing the reaction electrodes 2 through the matrix of wires 3. Further, to detect a state of reaction in each of the reaction electrodes 2, the conduction control device 4 is provided with a conduction state detector 5. By selectively applying a voltage to a specific reaction electrode 2, the reaction charged substance immobilized on the reaction electrode 2 is allowed to react specifically with a target charged substance. Further, the present invention also covers the detection panel 1 constituting the charged substance detector.
