Novel fabrication of bi‐metal oxide hybrid nanocomposites for synergetic enhancement of in vivo healing and wound care after caesarean section surgery

In the current study, bi-metal oxide hybrid nanocomposites prepared by cerium oxide (CeO2 ) nanoparticles are included into chitosan-ZnO composites for developing the potential materials of dressing the wound. The wound healing effect of prepared hybrid nanocomposites was evaluated regarding the surface morphology, functional groups, thermal degradation and composite size. The antimicrobial activity of chitosan-ZnO/CeO2 hybrid nano composites was tested against the pathogens of Staphylococcus aureus and Escherichia coli. The hybrid nanocomposites containing CeO2 -based chitosan and ZnO nanoparticles were taken for optimum dressing included in the vivo studies on the excisional wounds in wistar rats. After 2 weeks, it is seen that the wound treated with CS-ZnO/CeO2 hybrid nano composites consists of the significant dressing of nearly 100% compared with control which showed nearly 65% of wound closure. Finally, our reported results gave the proof in supporting the availability of CS-ZnO/CeO2 hybrid nanocomposites contains the dressing of the wounds for the treatment.
