Abstract:
1. A method of producing a polymer film with pores, comprising: providing a lipid; providing a pore forming template; dissolving the lipid and the pore forming template into a first solution; drying the first solution in order to create a lipid film with the pore forming templates dispersed throughout; hydrating the lipid film in order to create a second solution; extruding the second solution to form a unilamellar, uniform lipid film; providing a monomer in an effective amount so that a pore forming template spans a thickness of a formed polymer film in a lipid bilayer of the lipid film; providing a crosslinker; adding the monomer and the crosslinker to the extruded second solution; polymerizing the second solution in order to form the lipid bilayer with an interior, hydrophobic, polymer film with the pore forming templates dispersed throughout, wherein the polymer film has a thickness so that the pore forming template spans the thickness of the polymer film; dissolving the pore forming templates into a third solution by addition of a solvent; and removing the third solution by separation in order to leave a polymer film with pores of a uniform thickness and surface area.
