Monodomain gels with long aligned filaments of bundled nanofibers via the self-assembly of peptide amphiphiles. (a) Chemical structure of the peptide amphiphile used. (b,c) A peptide amphiphile solution colored with trypan blue injected into phosphate-buffered saline after heat treatment. (d) Optical polarizing micrograph of two stripe hydrogels. (e) Scanning electron micrograph of aligned nanofiber bundles in macroscopic strings. (f) Fluorescence micrograph of aligned calcein-labeled cells cultured on string.
