The Mechanism of Molecular Self-Assembly
At the heart of this technology is the self-assembly of short peptides. When placed in aqueous solutions, these self-assembling peptides undergo a phase transition, typically forming stable β-sheet structures in water. This process is highly sensitive to environmental conditions such as pH and ionic strength.
It is fascinating to observe how thousands of peptides self-assemble to form a single nanofiber, and subsequently, trillions of peptides or billions of nanofibers form the scaffold that can contain approximately 99.5% water. This high water content, combined with a high surface area-to-volume ratio, makes these peptide nanofiber scaffolds ideal for creating 3D environments that support cellular growth and interaction.
