We find that electrostatic interaction with the substrate dominates their adhesion behavior. Using polyelectrolyte coated surfaces with tailored charge densities, polyhedrons can thus be immobilized without complete spreading, which allows for further study of their mechanical properties using AFM force measurements. The elastic response of individual polyhedrons can be locally resolved, showing pronounced differences in stiffness between faces and vertexes of the structure, which makes these systems interesting as models for structurally similar colloidal scale objects such as viruses, where such effects are predicted but cannot be directly observed due to the smaller dimensions. Elastic constants of the wall material are estimated using shell and plate deformation models and are found to be a factor of 5 larger than those for neutral lipidic bilayers in the gel state. We discuss the molecular origins of this high stiffness}, language = {en} } @article{AnklamBehlerDingermannetal.2013, author = {Anklam, Elke and Behler, J{\"o}rg and Dingermann, Theodor and Elsinghorst, Paul and Fischer, Jochen and Esselen, Melanie and Foerster, Christian and Fr{\"o}hlich, Daniel and Goedel, Werner Andreas and Gregory, Peter and Grimme, Stefan and Hackenberger, Christian and Hansmann, Max and Heppekausen, Johannes and Hasenstab-Riedel, Sebastian and Kirchhoff, Erhard and Kratz, Karl-Ludwig and Krausz, Ferenc and Linker, Torsten and List, Benjamin and Ray, Kallol and Salzer, Reiner and Schubert, Ulrich and Schueth, Ferdi and Schwarz, Helmut and Schwietzke, Uta and Strey, Reinhard and Stumpf, Thorsten and Vaagt, Franziska and Volodkin, Dmitry and Wilke, Guenther and Zass, Engelbert and Zemb, Thomas}, title = {Awards}, series = {Nachrichten aus der Chemie : Zeitschrift der Gesellschaft Deutscher Chemiker}, volume = {61}, journal = {Nachrichten aus der Chemie : Zeitschrift der Gesellschaft Deutscher Chemiker}, number = {11}, publisher = {Ges.
