When we look at self-assembled nanofibers, we see a wide range of morphologies. These molecules can self-assemble into nanostructures of diverse sizes and shapes in response to environmental triggers like pH, temperature, and ionic strength. For instance, some peptides can self-assemble into nanofibers approximately 10 nm long, while others, such as spontaneously assembled nanofibers composed of hundreds of molecules, create complex, high-aspect-ratio geometries.
One of the most exciting aspects is the ability to program these materials. By associating a natural AMP with a β-sheet-forming synthetic peptide, scientists have created self-assembling AMPs that can form functional nanostructures. This modularity allows for the creation of self-assembling into Self-Assembled Peptide Nanofibers Designed as Biological one-dimensional nanofiber structure systems that are fine-tuned for specific environments.
