The Mechanism: How Nature Builds from the Bottom Up
The self-assembly of short peptides is a spontaneous, thermodynamic process where individual molecules organize themselves into highly ordered structures without external guidance. This self-assembly pathway starts from the peptide aggregates to the nanofibers, which then undergo further organization.
Many researchers have designed to self-assemble into nanofibers that exhibit remarkable stability. A key finding is that these self-assembling peptides form stable β-sheet structures in water, which serves as the backbone for their architectural integrity.
