(a) Alizarin red S staining of the electrospun sheet with different concentration of CP, confirms incorporation of CP in PGS/PCL polymer network. (b) XRD spectra of CP nanoparticles, PCL/PGS scaffold and composite scaffold. (c) TEM image of the electrospun composite nanofiber demonstrates embedding of CP nanoparticles within the fiber. (d,e) DSC curve of PGS/PCL scaffold with different concentration of CP scaffold during heating (d) and cooling (e).
