Abstract: A series of functional biomaterials with different sizes and morphologies can be constructed through
self-assembly, among which amphiphilic peptide-based materials have received intense attention. One main
possible reason is that the short amphiphilic peptides can facilitate the formation of versatile materials and promote
their further applications in different fields. Another reason is that the simple structure of amphiphilic peptides
can help establish the structure-function relationship. This review highlights the recent advances in the
self-assembly of two typical peptide species, surfactant-like peptides (SLPs) and peptides amphiphiles (PAs).
These peptides can self-assemble into diverse nanostructures. The formation of these different nanostructures resulted
from the delicate balance of varied non-covalent interactions. This review embraced each non-covalent
interaction and then listed the typical routes for regulating these non-covalent interactions, then realized the
morphologies modulation of the self-assemblies. Finally, their applications in some biomedical fields, such as
the stabilization of membrane proteins, templating for nanofabrication and biomineralization, acting as the
antibacterial and antitumor agents, hemostasis, and synthesis of melanin have been summarized. Further advances
in the self-assembly of SLPs and PAs may focus on the design of functional materials with targeted
properties and exploring their improved properties.
