ABSTRACT
In light of the need to create new materials that are safe for use in biomedical applications like wound healing and tissue engineering, a unique nanocomposite was formulated and produced in the current investigation. A biocompatible hydrogel was created using natural polymers xanthan gum (XG) and alginate (Alg). In order to enhance the mechanical characteristics of the natural polymer-based hydrogels, polyvinyl alcohol (PVA) was added to the hydrogel matrix. Subsequently, the XG-Alg hydrogel/PVA structure was combined with ZnMnFe2O4 nanoparticles in order to augment the antibacterial efficacy of the biomaterial. The XG-Alg hydrogel/PVA/ZnMnFe2O4 nanocomposite was analyzed using XRD, EDX, FT-IR, TGA, and FE-SEM techniques to determine its properties. In addition, the mechanical properties of the pure hydrogel were compared to those of the XG-Alg hydrogel/PVA/ZnMnFe2O4 nanocomposite. The nanocomposite exhibited a biocompatibility of 96.45 % and 94.32 % with HEK293T cell lines after 24 h and 48 h of incubation, respectively, in biological evaluations. Furthermore, a significant antibacterial efficacy was demonstrated against both gram-positive S. aureus and gram-negative E. coli bacteria. The findings suggest that the developed XG-Alg hydrogel/PVA/ZnMnFe2O4 nanocomposite has promising qualities for use in biomedical fields, such as tissue engineering.
