Since the bilayer lipid membrane (BLM) can be mixed with hydrophobic nanomaterials, In this study, we fabricated bilayer lipid membranes mixed with carbon-based nanomaterials. The membrane parameters were obtained by EIS measurement and fitting using an equivalent circuit. And we measured the photocurrent by irradiating blue, green or red laser on the membrane, there was a differece I_shift in the current flowing through the membrane between light irradiation and non-irradiation. As a resolt, there was a relationship between the capacity of BLM per unit area C_BLM/S_ap and the photocurrent difference I_shift.
