AI Technical Summary
In the existing technology, the preparation process of noble metal electrodes is complex and costly. The catalytic ability of a single noble metal electrode is insufficient. The active sites are severely lost during the modification of nanomaterials. The bonding of multi-metal electrodes is not strong, the conductivity is weak and they are easy to fall off. The preparation process is cumbersome.
A copper-based multimetal microelectrode was used to deposit gold nanoparticles in situ on the surface of the copper microelectrode via an electrochemical method. By adjusting the crystal plane ratio of the gold nanoparticles, a Cu-Au bimetallic electrode was formed, which simplified the preparation process and improved the catalytic activity and stability.
It achieves efficient glucose detection with a wide linear detection range, low detection limit, significantly increased electrode active area, good stability, and reduced cost of using precious metals.
