The invention discloses a multi-target analysis and detection device based on a closed forked bipolar electrode, which includes a substrate, and the substrate is provided with a detection reaction pool and a signal reaction pool separated by an insulating isolation belt, and the detection reaction pool A drive electrode and a detection terminal are arranged in the signal reaction pool, a drive electrode and a signal terminal are provided in the signal reaction pool, and the detection terminal is connected to the signal terminal through a conductor passing through an insulating isolation tape to form a closed bipolar electrode. The electrodes and the driving electrodes are connected to the power supply through wires, and the detection end is provided with at least two forks. Under varying voltages, by constructing an electrochemical sensing interface based on the detection target on each fork of the detection end of the forked bipolar electrode, the electrochemiluminescence signal generated by the signal end of the bipolar electrode can realize multiple detection. Simultaneous detection of targets, and can effectively avoid mutual interference between different detection objects on the fork. |
