Abstract
The present invention provides an electrochemical measurement method in which a plurality of samples comprising an analyte is respectively placed in a sensing chip with a plurality of wells. Since each of the wells is independently provided with an electrode and a labeled molecule, each of the plurality of samples generates a sensing signal after contacting the labeled molecule, and then the sensing signal in each of the plurality of wells is processed by a circuit disposed in each of the wells to correspondingly output the sensing signal, so that different analytes are independently analyzed in a single test to effectively improve the efficiency of electrochemical analysis.
