Deposition of highly resistive lipid bilayer on silicon–silicon dioxide electrode and incorporation of gramicidin studied by ac impedance spectroscopy

Effect of an electric field on a floating lipid bilayer: A neutron reflectivity study

“…The value of R m is in very good agreement with typical values of bilayer membranes resistance, around 0.9-1 MΩ.cm 2 for a high coverage of the substrate (see for example Ref. [21,22] usually found for supported bilayers (∼ 0.5 µF.cm −2 [21,22]). We have no explanation for this disagreement.…”

Membrane Electrochemistry: Electrochemical Processes in Bilayer Lipid Membrane

“…The conduction of incorporated ion-channels is affected as well [42]. It is impossible to form large area BLMs because of the size limitation [43]. Nonetheless they have been extremely valuable in the history of membrane research.…”

4 Electrochemistry of Biomimetic Membranes

“…138 The positively charged lipid was chosen to favor vesicle spreading on the negatively charged Si/SiO 2 surface. The impedance spectrum was simulated by an equivalent circuit consisting of two RC meshes in series, with the resistance R  of the aqueous solution in series with them.…”

“…229 On ITO electrodes, the presence of polymer cushions significantly reduces local defect densities and results in an electric resistance from 5 to 50 times higher than that of a lipid bilayer directly deposited on ITO. 8,138,139 A hydrophobic cellulose derivative provides not only an environment to a lipid monolayer, but also acts as an electric insulator with an electric resistance as high as 20 M cm 2 . When a lipid monolayer is deposited on a semiconductor surface pre-coated with such a polymer insulator, the whole system consists of a conductor-insulator-semiconductor set-up.…”
