DEVICE FOR MEASURING EXTRACELLULAR POTENTIAL, METHOD OF MEASURING EXTRACELLULAR POTENTIAL BY USING THE SAME AND APPARATUS FOR QUICKLY SCREENING DRUG PROVIDED THEREWITH

摘要

An extracellular potential measuring device capable of simply and highly reliably detecting a change in a minute electrical signal emitted by a biological sample, and an extracellular potential measuring method using the device, and an apparatus comprising the device, are provided. The extracellular potential measuring device measures an extracellular potential with great precision and a high output. The device comprises at least one well comprising means for holding a cell provided on a substrate, a measuring electrode for detecting an electrical signal of each of the at least one well, and a reference electrode. The cell holding means comprises at least one depression provided within the well, and has a throughhole at a bottom surface thereof, the throughhole being linked to means for suctioning the cell.
