Short peptide building blocks can organize into fibers, sheets and gels, connecting sequence-level interactions with material-scale mechanics and presentation.
Sequence encodes assembly
Hydrophobic patterning, charge, aromatic interactions, hydrogen bonding and backbone propensity influence whether peptides form soluble oligomers, fibers, sheets or gels. Small sequence changes can shift both structure and assembly kinetics.
Environment is part of the design
Concentration, pH, salt, temperature, shear and mixing history can alter nucleation and final morphology. Reproducible material studies therefore record preparation history as carefully as peptide identity.
Linking structure to function
Microscopy, spectroscopy, scattering, rheology and release measurements probe different scales. A convincing interpretation connects molecular organization, bulk mechanics and the intended experimental interaction without assuming that appearance alone establishes function.
