Abstract
The present invention is related to a membrane electrochemical signal detection system, which comprises a detection platform and a probe, wherein the detection platform comprises a substrate having a cavity; a hydrogel layer disposed in the cavity of the substrate; and a loading film disposed above the substrate and the hydrogel layer and having at least one through hole corresponding to the cavity forming at least one sample slot. Further, the surface of the probe is covered by an insulating layer, and a detecting metal is exposed at a tip portion of the probe.
