Fig. 7. P-XRD for (A) a magnified version of nano Fe-CNB to identify the different forms of iron present and the existence of graphitic carbon in the nano bio-composite, (B) P-XRD for nano Fe-CNB, calcium alginate bead, nano-Fe-CNB embedded CA beads and DOX-loaded nano-Fe-CNB embedded CA beads to determine the different forms of iron present in the nano-Fe-CNB and the crystalline nature of the material.
