obtained in the parent silver–chitosan dispersions and
to observe their distribution in the cast films. Electron
diffraction and energy dispersive spectroscopy (EDS) were
used to confirm the presence of silver in the samples. Silver
particle-size distributions in the dispersions or in the films
were determined statistically using the National Instruments
IMAQ Vision Builder software (N D 200 particles). Scanning
electron microscopy was carried out on a FEI Inspect
F50 scanning electron microscope used to visualize the
morphology of the films.
