The bilayer lipid membranes with ultra-thin thickness (4~5 nm) and high insulativity have great potential to serve as an insulating layer in bio-hybrid devices. At the same time, since bilayer lipid membranes can be formed by self-assembly, it can be used as a template to build functional membrane structures. Here, we proposed that by utilizing the outstanding properties of bilayer lipid membranes, functional bio-hybrid membranes can be readily formed by doping the lipid membrane with organic molecules.
In this work, copper phthalocyanine (CuPc), which has been widely used in the fields of catalysis, solar cells, and transistors, is used to dope the lipid membranes. To form the CuPc doped lipid membranes, CuPc and 1,2-diphytanoyl-sn-glycero-3-phosphochpline (DPhPC) were firstly dissolved in chloroform to form a clear solution with blue color. Then, the prepared solution was dropped onto water surface using a micro-syringe. Immediately, membranes with uniform blue color formed on the water surface. Finally, the formed membranes were transferred to a Si substrate pretreated with O2 plasma. The morphology of the formed blue membranes was investigated by atomic force microscope (AFM).
