47_46/2008Cover Picture: Cryo Electron Tomography Reveals Confined Complex Morphologies of Tripeptide-Containing Amphiphilic Double-Comb Diblock Copolymers (Angew. Chem. Int. Ed. 46/2008)

The anatomy of a copolymer is presented by N. A. J. M. Sommerdijk et al. in their Communication on page 8859 ff. The amphiphilic double-comb diblock polymer with oligo(ethylene oxide) and peptide chains aggregates to form complex shapes in aqueous solution. From cryo electron tomograms, 3D volumes were reconstructed (shown as a set of slices). Further visualization highlights branches and loops in a folded wormlike micelle (purple) and the channel structure inside a bicontinuous morphology (yellow).
