Chitosan-g-poly(acrylamide)/Zn (CPA-Zn) nanocomposite was synthesized using simple method in the presence of microwave radiations. CPA-Zn nanocomposite was characterized by various analytical techniques. CPA-Zn nanocomposite was used for controlled drug delivery of ofloxacin. The maximum drug release was 75% which was observed in acidic medium. The cumulative drug release and drug released kinetics of CPA-Zn was investigated. It was noticed that the drug release behavior depended upon the pH of medium as well as on the the nature of matrix. CPA-Zn nanocomposites were also studied for their antibacterial activity against E. coli bacteria.
