peptide-negative-effects Peptide nanotubes (PNTs) represent a fascinating class of nanomaterials formed through the self-assembly of peptides. These highly organized structures are characterized by their well-defined tubular shapes and possess remarkable thermal and chemical stability, making them promising candidates for a wide array of applications. The fundamental principle behind their creation is the inherent ability of specific peptide sequences to spontaneously arrange themselves into ordered, hollow cylindrical architectures作者：JD Hartgerink·1996·被引用次数：762—Peptide nanotubes, which are extended tubular β-sheet-like structures, are constructed by the self-assembly of flat, ring-shaped peptide subunits.. This process of self-assembly is driven by various intermolecular forces, including hydrogen bonding, hydrophobic interactions, and electrostatic forces, leading to the formation of peptide-based nanotubes.

The study and synthesis of peptide nanotubes have garnered significant interest due to their potential to mimic biological structures, such as membrane channels, and their versatility in various scientific and technological domains. Researchers are actively exploring the design, synthesis, and characterization of these complex nanostructures, aiming to tailor their properties for specific uses. The ability to control the self-assembly process allows for the creation of nanotubes with diverse morphologies and functionalities, opening doors to innovative applications.

The Self-Assembly Mechanism of Peptide Nanotubes

The formation of peptide nanotubes is a prime example of supramolecular self-assembly, a bottom-up approach to synthesizing novel nanomaterials. Amphiphilic peptides, which possess both hydrophobic and hydrophilic regions, are particularly adept at forming nanotubular structures. In aqueous environments, these peptides tend to arrange themselves such that their hydrophobic portions aggregate away from water, while their hydrophilic portions interact with it.作者：C Tarabout·2011·被引用次数：89—Supramolecular self-assembly is an attractive pathway for bottom-up synthesis of novel nanomaterials. In particular, this approach allows ... This can lead to the formation of various nanostructures, including nanotubes, where the peptides align to create a hollow core.

The specific sequence and structure of the peptide building blocks play a crucial role in determining the final nanotube architecture. For instance, cyclic peptides, amyloid peptides, and surfactant-like peptides have all been shown to self-assemble into nanotube structures. The extended tubular structures are often described as being similar to β-sheet arrangements, where peptide subunits link together to form the cylindrical wall. The precise control over the diameter and length of these nanotubes can be achieved through careful chemical modification of the peptide sequences or by controlling the assembly conditions, such as concentration, pH, and temperature.Self-Assembly of Peptide Nanotubes in an Organic Solvent
