Description

technical field

[0001] The invention relates to a microfluidic chip electrode for electrochemical detection and a manufacturing method of the microfluidic chip. Background technique

[0002] At present, the electrodes used in the electrochemical detection of microfluidic chips are mostly carbon fiber electrodes, sheet electrodes and noble metal electrodes, etc. The outlet positions of the electrodes and chip capillaries are not fixed, so the reproducibility of the sample detection current in the experiment is not good. . In order to solve the reproducibility problem in the electrochemical detection chip, many schemes of integrated electrodes have been proposed. The integrated electrodes have the characteristics of fixed relative positions, so the reproducibility is high. However, the way of integrating the working electrode is mostly to plate a thin layer of precious metal on the substrate of the chip. The electroplating process is very complicated, and sometimes it needs t...
