  • PEGylated peptide amphiphile nanofibers and methods of use
    Patent number: 11998589
    Abstract: Provided herein are peptide amphiphiles (PAs). In some embodiments, provided herein are PEGylated PAs (e.g. nonionic PAs). In some embodiments, the peptide amphiphiles are assembled into nanofibers. The nanofibers may further comprise a growth factor protein, which may bind to a growth factor binding sequence presented on the nonionic PA. In some embodiments, the nanofibers further comprise a charged peptide amphiphile. The charged peptide amphiphile may be bound to a growth factor protein. Further provided herein are methods of use of the peptide amphiphiles and compositions comprising the same, such as for regenerative therapy.
