Self-Assembly
Self-Assembly — The spontaneous organization of peptide molecules into ordered structures such as fibrils, nanotubes, or hydrogels driven by non-covalent interactions.
What Is Peptide Self-Assembly?
Peptide self-assembly is the spontaneous organization of peptide molecules into ordered nanostructures (nanofibers, nanotubes, vesicles, hydrogels) driven by non-covalent interactions: hydrogen bonding, hydrophobic effects, electrostatic interactions, and aromatic stacking. Self-assembling peptides create functional nanomaterials from simple, synthetically accessible building blocks.
Self-Assembling Systems
- Amyloid-like fibers: Short peptides (KLVFF, diphenylalanine) form beta-sheet-rich nanofibers analogous to amyloid
- RADA16: Ionic-complementary 16-mer forms hydrogels for tissue engineering
- Peptide amphiphiles: Lipid-peptide conjugates forming cylindrical nanofibers
- Coiled-coils: Leucine zipper peptides self-assemble into defined oligomeric states
