Fig. 1

Surface morphology and immunostaining of electrospun nanofibers. AFM images of (a) PLGA and (b) RGD/PLGA nanofiber matrices. c Immunofluorescence images of PLGA and RGD/PLGA electrospun fibers. RGD peptide-displaying M13 phages in the RGD/PLGA nanofibers were immunostained with the FITC-labeled anti-M13 phage antibody (green). All photographs shown in this figure are representative of six independent experiments with similar results
