Stable phospholipid membrane supported on porous filter paper.
A novel method to construct a stable and uniform phospholipid membrane of large area and good manipulability is reported. Using the Langmuir-Blodgett (LB) technique, a monolayer of phospholipid can be transferred to filter paper. The electrical conductance across the pores of the lipid membrane is about 1.8 X 10(-9) S/cm2, corresponding to the conductance of 10(-7)-10(-10) S/cm2 reported for bilayer lipid membranes (BLM) of phospholipids. A scanning electron micrograph demonstrated that the phospholipid membrane on the filter paper was uniform.
