Abstract

Photocleavage of a 2-nitrobenzyl group in a bioactive peptide amphiphile containing the Arg-Gly-Asp (RGD) epitope triggers a sol-to-gel transition as nanospheres are converted to nanofibers (see picture). This morphological change enhances the bioactivity of the nanostructures surrounding cells in three dimensions.
