Nanovesicles: Vesicle-Mediated Growth of Tubular Branches and Centimeter-Long Microtubes from a Single Molecule (Small 15/2013)

The spontaneous and reversible assembly of a new class of non-amphiphilic vesicle based on p-aminophenyl disulfide in a water/ethanol mixture is reported by S. Singamaneni and co-workers. On page 2611, a real-time view of their hierarchical transition reveals the rapid growth of nanostructures into vesicles, and vesicle walk and fusion on the sides and tips of the branches, leading to the formation of centimeterlong microtubes. The process is initiated and maintained by the convergent effects of cooperative hydrogen bonding, self-complementary primary amine groups, and the molecular nature of the solutions.
