This requires methods by which such membranes can One technique that in large quantities. One technique that was an important first step on this path now successfully demonstrated.

For their subnanometer channels Xu and her group used the organic nanotubes naturally formed by cyclic peptides – polypeptide protein chains at both ends at both ends, circle circle. Unlike preformed carbon nanotubes, these organic nanotubes are reversible , which means the size and orientation can be easily changed during the manufacturing process. For the membrane, is used and its employees Xu block copolymers – long sequences or blocks of a monomer molecule bound to blocks of another type of monomer molecule. Just as cyclic peptides assemble into nanotubes assemble assemble into well-defined block copolymers arrays of nanostructures over macroscopic distances itself.Asaid Khateb is neuropsychology at the University of Genf Hospitals.

Annals of Neurology releases articles of broad interest with potential for high impact strength in understanding the mechanisms and treatment of disorders of the human nervous system.
