Ultra sensitive biosensor for detecting bio-signal transmitters, and detector and detecting method using the same

摘要

The present invention relates to a novel use of a transfected cell as a biosensor, wherein the transfected cell expresses a receptor specific to a bio-signal transmitter, and a highly sensitive detector and a highly sensitive detecting method of a bio-signal transmitter using the biosensor. The bio-signal transmitter detecting technique according to the present invention has an advantage of being applied to a sniffer-patch method, and is capable of providing millisecond time resolution for detecting nanomolar levels of the bio-signal transmitter to be detected.
