An innovative experimental approach based on a microfluidic paper-based chip has been designed for specific detection of Escherichia coli (E. coli). The chip is fabricated for detecting E. coli in water samples. The main contents include the preparation of paper chips, lysis of E. coli on the chip, detection of E. coli, optimization of detection conditions, and detection of E. coli in actual samples. This experiment integrates cutting-edge disciplines, demonstrating robust comprehensive and innovative characteristics. It aligns with the practical education concept marked by the progression from “basic experiment → comprehensive experiment → research-oriented experiment”, effectively strengthening students’ capacities for problem analysis and solution.
