  Supramolecular Assembly of Block Copolypeptide at Different Processing and Solution Conditions

  Here we report the supramolecular assembly of poly( L-lysine)-b-polyglycine diblock copolypeptides at different solution conditions. Light scattering and confocal microscopy indicate that the supramolecular aggregates initially formed in solution are vesicles with a broad size distribution

  depending strongly on the initial processing conditions. The vesicles formed after multiple pH cycles appear independent of the initial processing conditions and are related to the thermodynamic nature of the assembled supramolecular aggregates. Circular dichroism results verify that this change in size observed over pH cyclings tracks with the conformation changes of the lysine block confined in the vesicle membranes. This appears interesting for peptosome-based materials

  implying a high level of fluidity in the membrane that allows the supramolecular aggregates formed in solution to respond to changes in pH. The results also show that the external stimulus

  which is the change of pH in this study

  provides an additional means to regulate polypeptide vesicle size and size distribution.

  The synthesis and characterization of melamine-based dendrimer/SBA-15-hybrids are reported. The current work demonstrates the ability to fabricate hybrid materials containing a high loading of organic moieties (30−35 wt %) that possess a well-defined structure.
