Abstract
A method for producing a structure comprising at least one membrane with continuous pores having a diameter range of 1 to 8 nm extending along plane, curved, cylindrical or vesicular surfaces consisting essentially of at least one layer of contiguous identical protein containing molecules which molecules are arranged to form a crystal lattice defining continous pores free of said molecules, the membranes being connected to or embedded in a support layer or the membranes being connected together to form a stable unsupported film comprising removing the cell contents from intact cells of microorganisms or breaking the intact cells and separating the membranes or membrane containing cell envelope fragments, suspending the membranes or membrane containing cell envelope fragments in a liquid medium, combining the membranes or membrane containing cell envelope fragments into a layer with a crystal lattice with continuous pores free of the protein containing molecules by depositing the membranes or membrane containing cell envelope fragments onto a support layer or introducing said fragments into a support layer or connecting said fragments together to form a stable unsupported film and a…
