Correction to Cisplatin-Loaded Graphene Oxide/Chitosan/Hydroxyapatite Composite as a Promising Tool for Osteosarcoma-Affected Bone Regeneration

In the original article, it was observed that the FTIR and XRD spectra of the samples GO/HAP/CS-1, GO/HAP/CS-2, and GO/HAP/CS-3 had similar patterns. Since then, the authors have recharacterized the samples (a) GO/HAP/CS-1, (b) GO/HAP/CS-2, and (c) GO/HAP/CS-3. The variation of CS concentration, the intensity of the C=O stretching vibration of −NHCO, and the N–H bending of −NH₂ were increased at 1682 and 1498 cm^–1, and other peaks are retained (Figure 1). Similarly, the crystalline nature of the XRD pattern slightly increases at the 2θ value of 25° with an increase of the CS concentration in GO/HAP/CS composites (Figure 2).

The figure changes do not affect the overall conclusion of the article.
