The produced nanocomposite was characterized by XRD and FESEM. The antibacterial activity of produced film was measured in different concentrations of silver nitrate against E. coli and S. aureus. The results showed high antibacterial activity in chitosan-Ag chitosan. It was also found that with an increase in the concentration of Ag nanoparticles in the nanocomposite to 0.03, the ant antibacterial effects increased and then remained constant. تفاصيل المقالة

The produced nanocomposite was characterized by XRD and FESEM. Antibacterial activity of the produced film was studied at different concentrations of silver nitrate againstEscherichia coliandStaphylococcus aureus.
