The ECL intensities increase at elevated electrode temperature, and the detection limit at 60℃ （electrode surface temperature） was about 10 times lower than that at 30℃. The results indicate that new heated electrode can be handled easily and can be mass produced, the difference between the electrodes was little. The stability of the HMEC was good since the electrode surface can hardly be destroyed during detection and storage.展开更多
