Methane is a common intestinal gas that has been linked to variety of gastrointestinal disorders. In this study, we prepared LIG-based electrochemical sensor modified with PEDOT:PSS/Au-Pt nanocomposites for high-sensitivity methane detection. LIG’s high porosity, flexibility, and excellent electrical conductivity are beneficial The PEDOT:PSS film electrodeposited on the electrode surface amplify signal further. synergistic effect bimetallic can improve catalytic activity increase specific area advantages active sites. experimental results show LIG wide linear detection range (2–500 ppm), low limit (about 0.36 sensitivity, good repeatability. easy manufacture, low-cost, operates at room temperature, limit, expected be used breath in future.
