Surface morphology and immunostaining of electrospun nanofibers. (A, B) SEM images of RGD-M13 phage/PLGA nanofibers. Fluorescence microscopic images of RGD-M13 phage/PLGA nanofibers (C) and pure PLGA nanofibers (D). RGD-M13 phages in RGD-M13 phage/PLGA nanofibers were immunostained with FITC-labeled anti-M13 phage antibody and fluoresced green.
