Cover Picture: 1D Arrangement of Au Nanoparticles by the Helical Structure of Schizophyllan: A Unique Encounter of a Natural Product with Inorganic Compounds (Angew. Chem. Int. Ed. 13/2005)

44_13/2005A linear array of nanoparticles can be generated by the use of an appropriate template. The cover picture shows a TEM image of such a 1D array of gold nanoparticles, aligned by the use of the β-1,3-glucan polysaccharide schizophyllan, which adopts a triple-helical structure in aqueous solution. In their Communication on page 2030 ff., S. Shinkai and co-workers describe how the hydrophobic inner cavity of the helix hosts the hydrophobic nanoparticles and aligns the guests along its length.
