FIGURE 2.
Impedance spectra of a gold-covered porous alumina substrate functionalized with a DPPTE submonolayer before (□) and after (○) spreading of a lipid droplet across the porous substrate. The solid line is the result of the fitting procedure using an equivalent circuit composed of a serial connection the electrolyte resistance Rel and the capacitance Cm of the lipid bilayer, which was determined to be Cm = 0.77 μF/cm2.
