EIS investigation of monoundecanoin addition to the tBLM platform. Time-resolve changes in conductance (Gm) and capacitance (Cm) signals following the addition of (A) 500 µM and (B) 125 µM monoundecanoin to the tBLM platform. The initial baseline measurements correspond to standard values indicating formation of the tBLM platform in PBS solution on the gold electrode. After 10 min of establishing the baseline, monoundecanoin was added (arrow 1) and incubated for 30 min before buffer washing was performed (arrow 2). C Summary of Gm shifts upon compound addition (top panel) and after buffer washing (bottom panel) relative to the tBLM baselines. Bode plots describing the phase shifts of the system from baseline signals in response to treatment with (D) 500 µM or (E) 125 µM monoundecanoin and buffer washing. F Schematic illustration based on the EIS data of how 500 µM monoundecanoin interacts with the tBLM and the resulting tBLM after monoundecanoin was removed by buffer washing
