[摘要]:Hexagonal peptide microtubes are spontaneously formed upon solvent thermal annealing. They have diameters on the order of micrometers and reach several millimeters in length. The microtubes evolve hierarchically in a hexagonal packing pattern from the molecular level to the micrometer scale. Such crystalline peptide microtubes serve as an active optical waveguide, allowing for light propagation along the long axis. |
