Fabrication of porous chitosan/silver nanocomposite film and its bactericidal efficacy against multi-drug resistant (MDR) clinical isolates

Multi-drug resistant (MDR) clinical isolates were used to test the bactericidal efficacy of the newly synthesized porous chitosan/silvernanocomposite film. The synthesized composite was characterized by using UV-Vis, FTIR, XRD and HRSEM analysis. The SEM images illustrate the presence of embedded silver nanoparticles (20-50 nm) throughout the films. Moreover, the presence of a small quantity of metal nanoparticles in the composite was enough to significantly enhance inactivation of MDR pathogens as compared with unaltered chitosan.
