Supramolecular Self-Assembly in Materials

Supramolecular self-assembly in biomaterials studies how small molecules — particularly peptide amphiphiles — spontaneously organize into ordered nanostructures such as nanofibers, hydrogels, and nanotubes through non-covalent interactions like hydrogen bonding, electrostatic forces, and hydrophobic effects. Because these structures can mimic the architecture and mechanical properties of native tissue, they are being developed as scaffolds for regenerative medicine, vehicles for controlled drug release, and platforms for directing cell behavior at the nanoscale. A central challenge is learning to program molecular geometry and chemistry precisely enough that the resulting assemblies are predictable, tunable, and stable under physiological conditions. Active research directions include designing stimuli-responsive materials that change structure in response to pH, temperature, or biological signals, and understanding how hierarchical assembly across multiple length scales governs the bulk properties of the final material.
