Targeting of vascular intervention by systemically delivered supramolecular nanofibers after balloon angioplasty is described. Tracking of self‐assembling peptide amphiphiles using fluorescence shows selective binding to the site of vascular intervention. Cylindrical nanostructures are observed to t...
