Abstract: This paper outlines a comprehensive, inquiry-based instrumental analysis experiment to integrate molecular imprinting technology into undergraduate education. The experiment commences with the fabrication of a streptomycin molecular imprinting electrochemical sensor (STR-MIM/GCE) via the electropolymerization method. Subsequent characterization of the sensor employs cyclic voltammetry and scanning electron microscopy. Utilizing potassium ferricyanide as a probe, a differential pulse voltammetry technique is developed for the electrochemical quantification of streptomycin, with milk serving as a real-world sample for testing. This experiment involves the modification and characterization of electrode surface, alongside the development and application of electrochemical analysis methods. The experiment uses readily available and cost-effective reagents, avoids the need for sophisticated instrumentation, and is designed with a duration suitable for undergraduate coursework.
