Scanning electron microscopy (SEM) images illustrating the degradation of nanocomposites (NC) and PCL with BW (PBW) after incubation in platelet-rich plasma (PRP). (A) NC before incubation shows distinct nanofiber spacing. (B) NC after 24 h in PRP exhibits altered surface morphology and a notable disappearance of the gaps between nanofibers. (C) PBW nanofibers before incubation display a uniform arrangement. (D) PBW after 24 h in PRP reveals merging of nanofibers, resulting in an increase in overall nanofiber size.
