Abstract Combining nanomaterials, electrochemical sensing technology and the content determination of the active ingredients of traditional Chinese medicine, an innovative experiment was set up for the students of traditional Chinese medicine. The contents of the experiment include the fabrication of sensors, performance testing, optimization of experimental conditions, separation and extraction of active ingredients of traditional Chinese medicine, covering a complete sample analysis process. This experiments involved the disciplines of inorganic chemistry, analytical chemistry, instrumental analysis and physical chemistry, with strong comprehensiveness. The experiment contains many processes, such as literature research, experimental plan design, exploration of electrochemical performance of sensors. Furthermore, the application of the single factor method in the experimental condition selection, the drawing of standard curve and the evaluation of the method accuracy by the recovery experiment were also involved. These processes enable students to closely combine theory and practice, explore scientific frontier, stimulate professional interest and self-confidence. Meanwhile, these processes help to cultivate students’ innovative thinking and enthusiasm for scientific research, and improve students’ practical application ability of knowledge.
