Supramolecular nanoassemblies such as scrolled/helical nanofibers and nanorings were constructed by controlling the length of the oligoether chains and inserting lateral methyl groups at the surface of the rod and coil domains in aqueous solutions.

AbstractVarious biofunctional hydrogel materials can be fabricated in aqueous media through the self-assembly of peptide derivatives, forming supramolecular nanostructures and their three-dimensional networks. In this study, we describe the self-assembly of new Fmoc-dipeptides comprising α-methyl-L-phenylalanine. We found that the position and number of methyl groups introduced onto the α carbons of the Fmoc-dipeptides by α-methyl-L-phenylalanine have a marked influence on the morphology of the supramolecular nanostructure as well as the hydrogel (network) formation ability.

Molecular Determinants

Elastin and elastin-related peptides have great potential in the biomaterial field, because of their peculiar mechanical properties and spontaneous self-assembling behavior. Depending on their sequences and under appropriate experimental conditions, they are able to self-assemble in different fiber morphologies, including amyloid-like fibers. In this work, we will review recent data on elastin peptides derived from exon 30-coded domain of human tropoelastin. This domain has been shown to be fundamental for the correct assembly of elastin. However, the N-terminal region forms amyloid-like fibers, while the C-terminal fragment forms elastin-like fibers. A rationale for the varied aggregation pattern has been sought in the molecular structure of the peptides. Minimal differences in the sequences, adopting alternative conformations, are shown to be responsible for the observed data.

The Relationship

We have demonstrated the self-alignment processes using surface tension of the resin material for the self-assembly systems. It has been known that the surface tension of the resin material is too low to achieve the self-alignment capability. This paper presents a fundamental concept and principles of resin self-alignment processes. The numerical analysis is conducted to enhance understandings of resin self-alignment behavior and the relationship between process-related parameters. It was proved that resin self-alignment is different from the oscillatory motion of solder self-alignment and shows overdamped motion by the experiment. We could achieve the precise alignment of less than 0.4 μm.
