Voltammetry is an important chapter and teaching difficulty in the course of Instrumental Analysis. However, the existing experiment teaching program has shortcomings in theoretical integration and application expansion. This paper introduces a cutting-edge research progress in material sciences, i.e., laser-scribed graphene technology, into voltammetry experiment teaching. The program enriches the experiment contents by introducing basic knowledge such as simulation of diffusion current theory and electrocatalytic phenomena, and extending applications such as vanillin detection in powdered milk. These new contents will help students to deeply understand the basic principles, research trends, and application value of the method. The comprehensive cost of the experiment is low, and the electrodes can be prepared in batches, thus making it suitable for experiment teaching.
