Self-assembling Venturi-like peptide nanotubes

We describe the design and synthesis of self-assembling peptide nanotubes that have an internal filter area and whose length and internal diameters, at the entrance and in the constricted area, are precisely controlled.

Large-diameter self-assembled dimers of α,γ-cyclic peptides, with the nanotubular solid-state structure of cyclo-[(l-Leu-d-MeN-γ-Acp)4-]·4CHCl2COOH

Dimeric nanotube segments with pore diameters of up to 17 A have been obtained by self-assembly from new alpha,gamma-cyclic peptides.
