“…The application of QDs mainly involved fields such as solar cell, laser, photoelectric diode, bio-targeting, drug delivery, protein tracking, cancer diagnoses, cellimaging, light-emitting diode, bio-labeling, modified electrodes and optical biomarkers [2]. It can predict that QDs showed immense and promising prospects in electrochemical as electrode modified materials due to their very small size, large specific surface area and excellent biocompatibility [3,4].
