Of the many types of molecules that are suitable for molecular self-assembly, peptides are unique in a way that a host of morphologies are possible during the spontaneous assembly process. Starting from a random arrangement of peptide molecules, there is an initial connection between the exterior assembly conditions and the assembled product at a certain later stage. In this study we have successfully achieved the formation of one-dimensional vertical nanowire arrays and two-dimensional spherulites via spontaneous crystallization of peptide molecules. Furthermore, we have effectively controlled the alignment and growth direction of peptide crystals through physical confinement of peptide melts with the aid of a soft PDMS mold. Apart from the morphological variations of self-assembled peptide molecules, we have also achieved a hybrid assembly of peptides with photoluminescent Alq3 molecules in which the photoluminescence was retained even after crystallization. |
