SIGNAL DETECTING SENSOR PROVIDED WITH MULTI-ELECTRODE

摘要

A sensor is provided with a plurality of electrodes disposed on a substrate for individually measuring each of the signals produced by biological samples held separately by each electrode, in which these electrodes comprise e.g. a biological sample-holding dent, a through-hole communicating with the dent and penetrating to the rear surface of the substrate, and an electrode element. A sensor is provided with a plurality of electrodes disposed on a substrate for individually measuring each of the signals produced by biological samples held separately by each electrode, in which these electrodes comprise a biological sample-holding dent, a through-hole communicating with the dent and penetrating to the rear surface of the substrate, an electrode element, and a lead wire from the electron element, each of which is so disposed that samples each held in the dent are electrically linked with one another. Independent claims are also included for the following: (1) An intercellular network analyzer equipped with the sensor, a means for housing cells disposed on the sensor, a means for maintaining conditions under which the cells in the container on such sensor can proliferate, a means to hold tightly the samples onto various electrodes of the sensors, a means to obtain electrical signals from the different electrodes, and a means for treating such electrical signals; and (2) A high-speed drug screening device equipped with the sensor, a means for housing cells disposed on the sensor, a means for maintaining conditions under which the cells in the container on such sensor can proliferate, a means for moving the cell container to the installed sensor, a means to hold tightly the samples onto various electrodes of the sensors, a means to obtain electrical signals from the different electrodes, and a means for treating such electrical signals.
