Figure 7: Nyquist plot of the millipore membrane (pore diameter 8 μm) impregnated with 320 mg/mL lecithine in tetradecane versus time: (1) 𝑡 = 0  s (beginning of the experiment), (2) 𝑡 = 1 8 0 0  s (30 min), (3) 𝑡 = 3 6 0 0  s (60 min), and (4) 𝑡 = 5 4 0 0  s (90 min; after the end of the experiment). The BMM impedance remains over 3 MΩ. This means that the BMM is intact.
