INVESTIGATIONS ON CHITOSAN/α-Fe O NANOCOMPOSITE FOR 2 3 EFFICIENT ANTIBACTERIAL ACTIVITY

Abstract

Chitosan capped with α-Fe O nanocomposite was prepared by simple chemical precipitation method. The synthesized 2 3 Chitosan/α-Fe O nanocomposite was characterised by FTIR, UV–visible spectroscopy and XRD analysis. These results 2 3 showed that α-Fe O nanoparticles were successfully grown on the surface of chitosan. The FTIR vibrational peaks conrm the blending between 2 3 Chitosan and α-Fe O nanoparticles. Chitosan/α-Fe O nanocomposite. 2 3 2 3 Ultraviolet-Visible absorption spectra explain the optical property of The sharp peaks in XRD pattern indicate the increase in crystallinity nature of Chitosan/α-Fe O nanocomposite. Finally, the prepared Chitosan/α- 2 3 Fe O nanocomposite was tested for antibacterial activity against Staphylococcus aureus and Escherichia coli.
