Nanofibers have become a key component in tissue engineering due to their ability to mimic the nanoscale architecture of natural tissues. Three main techniques are used for nanofiber synthesis: electrospinning, self-assembly, and phase separation. Electrospinning is the most widely studied and promising method, allowing the production of nanofibers with high surface area and porosity, which are beneficial for cell adhesion, proliferation, and differentiation. These nanofibers can be used as scaffolds for various tissues, including musculoskeletal, skin, vascular, and neural tissues, as well as for drug delivery. Electrospinning involves applying an electric potential to a polymer solution, which causes the solution to form nanofibers. The process can be controlled to produce fibers with specific thickness, composition, and orientation. Natural and synthetic polymers such as collagen, chitosan, hyaluronic acid, and synthetic polymers like PLA, PCL, and PLGA are commonly used to produce nanofibers. These nanofibers can be tailored for specific applications by adjusting parameters such as polymer concentration, electric potential, and collector design. Self-assembly involves the formation of nanofibers through the self-organization of peptide amphiphiles, which can create thermally stable, protein-like structures. These structures can be used as scaffolds for tissue engineering and have shown potential for improving biocompatibility and cell response. Phase separation is another technique that produces nanofibrous scaffolds with high porosity and mechanical strength, suitable for tissue engineering applications. Nanofibers have been used in various tissue engineering applications, including bone, cartilage, ligament, skeletal muscle, skin, vascular, and neural tissues. They provide a suitable environment for cell adhesion, proliferation, and differentiation, and can be used for controlled drug delivery. The development of nanofibers has significantly advanced the field of tissue engineering, offering new possibilities for the regeneration of damaged tissues and the treatment of various diseases.Nanofibers have become a key component in tissue engineering due to their ability to mimic the nanoscale architecture of natural tissues.
