facile preparation of silver nanoparticles and antibacterial chitosan-ag polymeric nanocomposites

Silver nanostructures as an effective antibacterial materials were synthesized via three various hydrothermal, sono-chemical and microwave methods using water as a green solvent. then chitosan-ag polymer based nanocomposites were made by a fast chemical procedure. the influence of power, temperature and time on the morphology and particle size of the products was investigated. scanning electron microscopy (sem) approved that mono-disperse nanoparticles were achieved using all three procedures. x-ray diffraction (xrd) and fourier transform infrared (ft-ir) spectroscopy confirmed preparation of pure products. the antibacterial behaviour of chitosan-ag nanocomposites was evaluated using degradation of e coli bacteria. the results show a nanocomposite with applicable antibacterial performance in burn wounds.
