The modification of solid substrates and membranes using biomaterials is an attractive field of research for developing new devices such as biosensors, structured multilayers, biomembrane mimetics, biomaterial coatings for therapeutical applications, etc. (Goodsell 2004; Sackmann 1996). Particularly, lipid-layer deposition on membrane supports might improve their biocompatibility, but it might also affect membrane transport parameters and, consequently, its functionality.

Changes in electrical and transport parameters for a hydrophilic regenerated cellulose membrane (RC sample) as a result of lipid surface deposition (RC/LL sample) were studied by measuring impedance spectroscopy (IS) and membrane potential. Lipid-layer (glyceryl tristearate as main lipid with L-α-phosphatidylcholine and sodium taurocholate as surfactants) deposition on RC supports was already described (Benavente et al. 2011).

Impedance is an a.c. technique for determining membrane electrical resistance and...
