Provided herein are peptide amphiphiles (PAs) and supramolecular PA nanostructures that mimic brain derived neurotrophic factor (BDNF), a growth factor that induces neuronal survival, maturation, and increased electrical activity. In particular, injectable biomaterials comprising BDNF mimetic PAs are provided, as well as methods of using BDNF mimetic PAs for the treatment or prevention of neurological injuries, diseases, and disorders.

The disclosure relates to compositions and superstructures comprising peptide amphiphiles. In some aspects, the disclosure relates to compositions and superstructures comprising host and guest peptide amphiphiles, wherein the host and guest moieties of the peptide amphiphiles interact via non-covalent interactions to form a supramolecular assembly, such a superstructure. In some aspects, the superstructure further comprises a bioactive moiety. Suitable bioactive moieties may be selected to promote cell growth, migration, and/or differentiation.
