The formation of peptide nanotubes is rooted in the intrinsic properties of peptides, which are short chains of amino acids linked by peptide bonds. Through specific chemical interactions, these peptides can spontaneously assemble, leading to the creation of intricate nanostructures. This process often involves the formation of extended tubular structures, sometimes described as extended tubular β-sheet-like structures, built from the self-assembly of flat or ring-shaped peptide subunits. The precise arrangement and interactions between these subunits dictate the final morphology and properties of the resulting nanotubes. Research into self-assembled peptide nanotube systems is actively expanding, leveraging techniques like X-ray scattering to elucidate their multiscale structure.

A key aspect of peptide nanotube formation is the role of intermolecular forces, including hydrogen bonds, which play a crucial role in stabilizing the nanotube architecture. For instance, some peptide nanotubes are formed via a network of hydrogen bonds between the peptide backbone and water molecules, which can even permeate the interior of the nanotube. This intricate interplay of molecular forces allows for the precise control over the design, synthesis, and characterization of complex nanostructures. The diversity of peptide sequences and their inherent chemical properties offer a vast landscape for engineering peptide-based nanotubes with tailored functionalities.

The versatility of peptide nanotubes is further underscored by the different classes of peptides that can undergo self-assembly into these structures. This includes cyclic peptides, amyloid peptides, and surfactant-like peptides. For example, several surfactant-like peptides undergo self-assembly to form nanotubes and nanovesicles with specific diameters and helical twists, often ranging from 30 to 50 nm. The development of new hybrid α,d-cyclic peptides (D,L-α,d-CPs) has also been explored, demonstrating their self-assembling properties and ability to form nanotubes.Self-assembling peptidesare a category of peptides which undergo spontaneous assembling into ordered nanostructures.
