Abstract: This study presents a novel training experiment rooted in the behavior of surfactants at interfaces and the relationship between the properties of gating liquids and the transmembrane pressure threshold of gases in a liquid gating system. By employing a liquid gating teaching analyzer (pressure threshold analyzer), we facilitate visual substance detection through a liquid gating mechanism. This experiment, part of the undergraduate “Chemical Metrology Experiments” course within the Chemistry “101 Plan”, exemplifies the concept of dipole-induced liquid gating for visual substance detection. The primary objective is to cultivate students’ ability to integrate theoretical knowledge with practical application, encourage the utilization of learned concepts, and enhance their innovative practical skills.
