ABSTRACT. The focal point of this paper, nanocomposite of hybrid materials Chitosan(CH) with α -Fe2O3, Chitosan with γ-Fe2O3 was synthesized.  The α-Fe2O3 and γ-Fe2O3 nanoparticles were synthesized by the self-assembly and microwave method and characterized. The average particle size was found to be 27–30nm by XRD and AFM. The synthesized nanoparticles were dispersed into the prepared chitosan (CH) solution. After the dispersion, the CH-α-Fe2O3, CH-γ-Fe2O3 nanocomposite was subjected to characterizations such as UV-Visible, XRD and SEM with EDX.  The CH-α-Fe2O3 nanocomposite to impart good antibacterial activity compared to that of pristine α -Fe2O3 and pristine chitosan. Electrochemical response studies were carried out using CH-γ-Fe2O3 nanocomposite with carbon paste modified electrode.

Keywords: nanocomposite, self-assembly, microwave, iron oxide, chitosan
