Problems solved by technology

The existence of the labeling process can easily cause interference to the detection system, causing errors in the measurement accuracy of the system target, and the generated interference signal will also affect the specificity of the measurement; and the existence of the labeling process further increases the detection cost.

[0007] From the above analysis, it can be seen that although the electrochemical immunoprotein chip has broken through the limitation of single channel at this stage, it still needs to be further developed in terms of integration and miniaturization, so that the advantages of electrochemical detection in immunoprotein chips can be fully utilized.
