“…The diffraction peaks of Yb 2 O 3 were determined at 2θ = 20.5, 29.3, 34.1, 44.06, 49.1, 53.9, and 58.4°, which correspond to Miller’s indices (211), (222), (400), (622), (440), (611), and (622) [ 19 ]. The high, intense peak was at 29.3; however, peaks at 49.1 and 58.4° were ascribed as weak diffraction peaks that refer to the cubic structure of Yb 2 O 3 [ 20 ]. In addition, V 2 O 5 exhibited several peaks at 2 θ = 15.08, 20.6, 26.03, and 30.7°, which correspond to the orthorhombic structure of V 2 O 5 with Miller’s indices (200), (001), (110), and (301) [ 21 ].…”

In the current work, chitosan (CS)–metal oxide nanohybrid (MONH) composites are prepared via combining CS with MONH made of vanadium oxide (V2O5), ytterbium trioxide (Yb2O3), and graphene oxide (GO) to generate promising wound dressing materials using the film-casting method. The developed nanohybrid@CS was examined using techniques such as Fourier-transform infrared spectroscopy (FTIR), X-ray powder diffraction (XRD), scanning electron microscopy (SEM)/energy-dispersive X-ray spectroscopy (EDX), and thermogravimetric analysis (TGA). For Yb2O3@CS, the surface morphology was shown to be a rough and porous surface with pores that ranged in size from 3.0 to 5.0 µm. For CS with Yb2O3, Yb2O3/V2O5@CS, and Yb2O3/V2O5/GO@CS, the contact angles were 72.5°, 68.2°, and 46.5°, respectively. When the nanohybrid@CS was in its hydrophilic phase, which is good for absorbing moisture and drugs, there was a notable decrease in angles that tended to rise. Additionally, the inclusion of MONH allowed the cell viability to be confirmed with an IC50 of 1997.2 g/mL and the cell growth to reach 111.3% at a concentration of 7.9 g/mL.
